The ongoing automation of driving functions in cars results in the evolution of advanced driver assistance systems (ADAS) into ones capable of highly automated driving, which will in turn progress into fully autonomous, self-driving cars. To work properly, these functions first must be able to perceive the car's surroundings by such means as radar, lidar, camera, and ultrasound sensors. As the complexity of such systems increases along with the level of automation, the demands on environment sensors, including radar, grow as well. Particularly, resolution as well as dynamic range in all four radar dimensions are to be improved. For radar performance to meet the requirements of self-driving cars, straightforward scaling of the radar parameters (e.g. bandwidth, sampling rate, aperture) is not sufficient. Rather, fundamentally different approaches are required, including the use of more sophisticated signal processing algorithms as well as alternative radar waveforms and modulation schemes. In addition, since radar is an active sensor, interference becomes a crucial issue as the number of deployed automotive radar sensors increases.
The talk gives an overview of the challenges that arise for automotive radar from its development as a sensor for ADAS to a core component of self-driving cars. It summarizes the relevant research and discusses topics related to high-performance automotive radar systems, such as novel waveforms and signal processing algorithms, multiple-input multiple-output (MIMO) radar, synthetic aperture radar, and cognitive interference avoidance.
