COMBINATION OF LFMCW AND FSK MODULATION PRINCIPLES FOR AUTOMOTIVE RADAR SYSTEMS Symposium Topic: Automotive Radar

High performance automotive radar systems are currently under development for various applications. Comfort systems like Adaptive Cruise Control (ACC) are already available on the market as 77 GHz radars. Target range and velocity are measured simultaneously with high resolution and accuracy even in multi-target situations but the measurement and processing time to detect the relevant object is approximately 100 ms. Future developments will be more concentrated on safety applications like Collision Avoidance (CA) or Autonomous Driving (AD). In this case the requirements for reliability (extreme low false alarm rate) and reaction time (extreme short delay) are much higher compared with ACC systems.
