Automotive Anti-Collision Radar Signal Processing System Design Based on DSP

Abstract:

The principle of the frequency modulated continuous wave radar for measuring distance and velocity and signal processing method are described in this paper; To solve the signal processing problem for FMCW automotive anti-collision radar system ,the radar signal processing circuit is researched and designed, including the design of corresponding gain control amplifier circuit, power supply and filter circuit, external memory circuit ,power supply circuit ,signal interface circuit, and analyzed the results of the measurement for system. Experiments showed that the system achieved good accuracy design effect and higher measurement precision and has certain positive role to improve vehicle safety.
