The implementation approach of small high precision signal processing system of collision avoidance radar is studied directing against the existing problems in domestic automotive anti-collision radar field, and signal processing flow is analyzed in detail and appropriate signal processing methods of radar is determined. System parameters suitable for driving environment are computed combining with the system structure and processing scheme and their effectiveness is verified through system simulation. Under the condition of miniaturization and low cost it is proposed to improve the targets range resolution based on Super-SVA method. It is assured that the detection performance of radar system will not be limited by costs problem. Finally the outfield functional testing with the prototype has been achieved and the feasibility of system scheme is verfied by the analysis results of the test data.
