Aiming at the existing problems in the field of domestic automotive anti-collision radar, the realization of a miniature high-precision collision avoidance radar signal processing system is studied. The signal processing flow is analyzed in detail to determine the appropriate radar signal processing method. Combining with the system structure and processing scheme, the system parameters suitable for the driving environment are calculated, and the validity of the system is verified through system simulation. In the condition of miniaturization and low cost, the method based on Super-SVA is proposed to improve the target distance resolution. Ensure radar systems do not limit their detection performance due to cost issues. Finally, the prototype of the instantiation of the field function test, test data analysis results verify the feasibility of the system program.
