About Automotive Radar Systems
Smart and powerful radar sensors in the 24 and 77 GHz domain for automotive applications require extremely high performance figures in terms of measurement accuracy. Additionally, very high resolution in target range, azimuth angle and Doppler frequency is necessary for reliable driver assistance and safety systems.
A real technical challenge in this case and in these automotive radar systems is the simultaneous measurement of target range, azimuth angle and radial velocity, especially in multiple target situations. These general requirements particularly affect the waveform design and the azimuth measurement technique. Therefore, continuous wave (CW) radar systems with very specific frequency modulations in combination with the monopulse technique haven been developed.
Powerful radar systems for the automotive sector are currently under development or in a research stage for various applications, amongst them Adaptive Cruise Control (ACC) which has already been introduced to the market (e.g. Mercedes S class, Volkswagen Phaeton or Audi A8), stop-and-go (City ACC), lane change assistance, turn assistant and even pre-crash systems. But there are many additional applications for such smart radar sensors for example environmental control and surveillance of industrial facilities.
Who should attend / Target audience
The course is suitable for engineers and researchers working in the fields of radar system design in general and in automotive radar systems in particular. Frequency coding schemes for CW radars will be discussed in combination with monopulse techniques based on a new patch antenna design. All the digital signal processing techniques will be considered, such as target detection based on new CFAR schemes, estimation, and target tracking procedures. Furthermore some radar system networks will be considered for various applications.
The course will be of particular interest to all engineers who design and develop high performance and smart radar systems in the radar and automotive industry.
Brief Course Outline
One important step in the design and development phase of a radar system is the waveform design procedure. Frequency coded and linear frequency modulated continuous wave (LFMCW) radar sensors have the advantage of high resolution performance in target range and radial velocity but they require a long measurement time. Therefore, new intertwined waveforms, like FSK or combinations between FSK and FMCW will be discussed in detail to demonstrate the technical differences and advantages.
All other radar signal processing topics, such as CFAR detection, parameter estimation, azimuth angle measurement, target tracking, and even target recognition will be covered by the tutorial. Some experimental systems and measurement results from real urban scenarios are used to explain and demonstrate the technical challenges of automotive radar sensor development.
Course topics will include:
- Introduction to Automotive Radar Systems
- System requirements and technical challenges
- Simultaneous range and Doppler frequency measurement
- Waveform designs, technical differences and advantages
