Q. You are CTO of UniqueSec and chair of IEEE SA P3116. Please briefly introduce yourself to Korean readers.

A.I graduated top of my class in B.Sc. and M.Sc. of Communications Engineering, and after a year of teaching at university, I was snapped up by a Swedish startup in the area of 카지노사이트추천 signal processing, UniqueSec AB.
The problem to solve was all the way from RF to baseband, and from antenna to signal processing. So, I was always engaged w카지노사이트추천h the whole problem; from the beginning to the end, which gave me a big picture and view on the subject.

Evaluating our 카지노사이트추천 solutions in the adverse weather of winters in Sweden was difficult and this sparked the need for an in-lab testing system. Using signal processing and 카지노사이트추천 knowledge in my toolbox, I invented a system for generating virtual targets in spectrum domain. And I made the first prototype of it in 24 GHz with all available equipment in our lab. To my surprise, the first patent application on this technology, named ASGARD, was granted within 9 months given that the method is unique and unorthodox in 카지노사이트추천 testing field.

ASGARD invention changed the company’s business to automotive 카지노사이트추천 testing, where I became familiar with IEEE Standardization Association activities in automotive area. In 2018, I saw the missing place for automotive 카지노사이트추천 standard and since then I have been active in forming an international alliance to start such standardization effort. Since it has started last year, I am the leader for 카지노사이트추천 testing in IEEE P3116.



Q. The words such as 카지노사이트추천 alone can't do it, Camera can do it alone, Lidar should be added, etc. may be due to the limitations of 카지노사이트추천 in some way. On the other hand, some say that the cost advantage should make 카지노사이트추천 a key sensor in all areas of the autonomous driving level. What do you think about it?

A. The fact is, all sensing technologies including camera, lidar and 카지노사이트추천, have their own limitations. Neither of these sensor can work alone in all situations. So I believe some sort of redundancy is always needed to ensure that the reliability we expect in automated driving can be achieved. 카지노사이트추천 is the least expensive sensor on a car after ultrasonic, but it has other strong points which make it a key and critical sensor on vehicles; it measures distance and speed directly with a good resolution; it operates at night and its performance degrades less by harsh weather conditions compared with other sensors.

However, 카지노사이트추천s can be limited in angular resolution and Field-of-View. Recently new 카지노사이트추천s, called 4D or imaging 카지노사이트추천s, provide a high-resolution perception of the surrounding which is comparable with lidars, only at a fraction of price. In general, 카지노사이트추천s are dependable and robust sensors, a must-have for higher automation levels.



Q. Improvements such as imaging 카지노사이트추천 are being made in the 카지노사이트추천 scene. As autonomous driving advances, the reliability of 카지노사이트추천 should be higher, but I know that 카지노사이트추천 still has problems such as false positive, low angular resolution, and mutual interference. You said 카지노사이트추천 is the most reliable sensor for level 4 and above. Why? How can we further improve 카지노사이트추천 performance?

A.There are huge advancements in 카지노사이트추천 technology which not only have improved their performance, but also take 카지노사이트추천s to a whole new level. New 카지노사이트추천s are said to see around the corner. One of the trends is the use of large transceiver channels, for instance 48 or 72 channels, in many new-coming 카지노사이트추천s, leading to very large virtual arrays of antennas which improves angular resolution. Another method is using different 카지노사이트추천 signals such as PMCW (Phase Modulated Continuous Wave) that makes the 카지노사이트추천 less susceptible to interference. New antenna technologies, like meta materials and gap antenna also help achieve higher angular resolution with wider FoV. Some new 카지노사이트추천s even utilize multiple ISM bands. So the 카지노사이트추천 signal is not designed only for one frequency band, e.g. the typical 76-81 GHz, but it contains signals from below 10GHz to 77GHz range. This reduces the risk of interference, reduces false detections and increases availability of the sensor.

As you know, higher automation levels demand higher accuracy, resolution, reliability and dependability. I think future generation of 카지노사이트추천s is ahead of cameras and lidars in these aspects.



Q. I am writing articles about the role of AI in the automotive industry. How, where, and how much can AI contribute to improving 카지노사이트추천 performance?

A.AI is and will be a big part of the future of sensor development especially in 카지노사이트추천 domain. AI and machine learning are powerful tools for target association and tracking in 카지노사이트추천 post processing. Training AI, or a neural network, depends heavily on training data. For cameras, training data can be collected and annotated ? by human eye. This is a challenge for 카지노사이트추천s. Firstly because the 2D signal of 카지노사이트추천 cannot be comprehended by human eye. And secondly, when recording a real scenario by a 카지노사이트추천, you can never know how much of the scenario the 카지노사이트추천 captured in its signal. 카지노사이트추천 target simulators, are practical to produce high-quality annotated data thanks to the ground truth reference. Uniquesec’s ASGARD system is an example of such simulators which can generate quite realistic annotated data for 카지노사이트추천-based AI systems in autonomous vehicles.

AI has a lot of possibilities for further development; by applying heuristic information into its training. For instance, in case of 카지노사이트추천 tracking, it is helpful to use map information.







Q. How are 카지노사이트추천 testing methods improved, with what needs? How important is this to improving 카지노사이트추천 performance, autonomous driving? why do we need the IEEE SA P3116 standard now? Is it because it relates to other standards progress like NCAP, ASAM?

A.For testing a complete automotive 카지노사이트추천, with its hardware and software, over-the-air (OTA) testing is necessary. The most commonly used method has been driving expeditions, where the tests happen in a controlled situation with a human driver involved. This is not particularly helpful for evaluating 카지노사이트추천 performance in dangerous situations and accident scenarios; besides, there is no access to ground truth data and the tests are not reproducible.

In recent years, 카지노사이트추천 target simulators are advancing for this purpose. They enable repeatable in-lab testing with access to ground truth.

Typical RTS technologies are based on implementing time delays and are originated from military. They used to be and some are still limited in certain features, for example number of virtual targets or minimum range of targets. Newer technologies, such as UniqueSec’s ASGARD offer more flexibility in terms of number of targets, minimum distance, etc. which makes it better suited to automotive 카지노사이트추천 validation.

Advances in 카지노사이트추천 technology drive the trends on RTSs. For example, evaluation of high-resolution imaging 카지노사이트추천s in dense traffic situations requires hundreds of virtual targets with arbitrary trajectories. OEMs and tier-1s also have different testing demands.

Certain requirements for RTSs are more highlighted as the need for thorough testing of 카지노사이트추천s and 카지노사이트추천-based ADAS/AD functions increases. Creating targets with high angular resolution and Hardware-in-the-Loop (HIL) testing are two of them. There is a shift from mechanically rotating antennas towards using larger antenna arrays, such as Keysight’s solution, and MIMO methods for electronic angle generation in Uniquesec’s approach.

Near to 카지노사이트추천 operation, size of RTS, as well as real-time operation are key requirements for HIL testing. I know many solutions that need a 1-2 meters space, causing challenges due to space limitation in test beds. ASGARD can operate in very close vicinity to 카지노사이트추천 under test, e.g. 20 centimeters. We have successfully integrated it for closed loop HIL testing of Bosch 카지노사이트추천 on a Porsche last year.

We are at a point where many new 카지노사이트추천s are emerging, ADAS is moving towards automation and fully autonomous vehicles, a lot of questions and concerns are being raised about the safety of automated driving, and the society needs to trust this technology. Also, there are many standardization activities by different bodies addressing various aspects of automated driving, such as test scenarios, camera image quality (P2020), assumptions in automated driving, etc.

카지노사이트추천 performance, however, is not specifically addressed by NCAP, ASAM, ISO or other standards. Standardization on spectrum usage and frequency band of automotive 카지노사이트추천s is done by ETSI and FCC. IEEE P3116 for automotive 카지노사이트추천 performance metrics and testing methods started (by three corporations from three continents) to define minimum requirements on 카지노사이트추천 sensors for ADAS/AD applications. We have participation of industry leaders such as NI, CAERI, UniqueSec, Keysight, Qualcomm, Infineon, ZF, NXP, Huawei, Spartan 카지노사이트추천, Yokosuka Telecom Research Park, and Cloudwalk.





ASGARD1 system


Q. Please also introduce ASGARD1 of UniqueSec. Could I interpret the fact that you and your company are playing an important role in this 카지노사이트추천 activity to mean that the solution is just as innovative?

A.ASGARD is a 카지노사이트추천 target simulator which emulates 카지노사이트추천 echos by manipulating 카지노사이트추천 signal in spectrum domain. The 카지노사이트추천 target signature is represented in frequency and it will be added to the 카지노사이트추천 signal without any down-conversion and delay. The technology for this frequency-based RTS is patented by UniqueSec around the world, including South Korea.

ASGARD has been awarded in Auto-sense 2019 as the best validation tool. 카지노사이트추천 has several advantages that typical delay-based technologies missed, including the possibil카지노사이트추천y of:
Creating perception of extremely short range and long range targets in the same scenario,
Generating multiple targets w카지노사이트추천hout the need for hardware modification,
Fully electronic angular perception generation,
Real-time HIL integration w카지노사이트추천h various environment simulator such as IPG Carmaker, Siemens PreScan, CarSim, Vector Dyna4, etc.,
Generating micro-Doppler signature for vulnerable road user simulation,
Generating interference,
Testing MIMO 카지노사이트추천s.

ASGARD has a digital back-end, an RF front-end and the state of the art software. You can see ASGARD in front of an Aptiv production 카지노사이트추천 in the picture.

P3116 is going to define performance requirements on automotive 카지노사이트추천s in different use cases, 카지노사이트추천 types, scenarios, and for all automation levels. Of course, verifying and evaluating 카지노사이트추천 performance places a huge burden on the standard, which calls for innovative methods in 카지노사이트추천 performance analysis.
This standard is going to be instrumental for the future of automated driving since 카지노사이트추천 sensors are integral for ADAS and autonomous vehicles.




AutoSense awards 2019


Q. The IEEE SA P3116 Working Group started last year, right? Short, but formally and informally, what are the discussions so far and future developments?

A.Yes, the proposal for this standard was approved by IEEE SA last September and the initial meeting was held in December. So far, we have discussed the procedure, DOs and DON’Ts for standard development in IEEE SA. We are in the process of creating the table of contents now and have agreed about the main pillars of this standard will contain. At a quick look, it includes (i) static performance metrics, (ii) dynamic and scenario-related performance metrics, (iii) interference and (iv) 카지노사이트추천 testing methods. Based on this, four subgroups of IEEE P3116 are finalizing the table of contents in the next few months. The standard is planned to be developed in five years. I believe it is a big effort which calls for participation and contribution from all stakeholders and experts of the field.



Q. There are so many Korean and foreign companies related to 카지노사이트추천 in Korea. but, Is there any participation of Korean companies or other stakeholders in the standardization work?

A. We don't have any Korean participation in P3116 working group yet. Thus, I’d like to take the opportunity and invite all Korean OEMs (e.g. Hyundai), Tier-1s (e.g. Mando), Tier-2s (e.g. LG electronics), research and/or 카지노사이트추천 institutes to join our efforts in P3116 working group.



Q. Tell us about the reputation of UniqueSec and 카지노사이트추천s solutions in the global and Korean automotive industry. Finally, what would you like to say to our readers in Korea regarding UniqueSec's business and IEEE SA P3116?
