In recent years, with the continuous maturity of integrated circuit and antenna technology and the continuous reduction of component cost, automotive radar products are continuously developed and applied. As an important part of intelligent vehicle and intelligent transportation, the frequency of vehicle borne millimeter radar has been paid special attention by the national radio management department. The purpose of this study is to explore the mechanism and advantages of sparse array technology in vehicular millimeter wave radar. Based on the sparse array technology, the array structure is optimized, and the vehicle borne millimeter wave radar is simulated. The experimental results show that, compared with simulated annealing algorithm, the optimal and worst PSLL of sparse array algorithm are improved by 5dB and 2dB respectively, the optimal peak sidelobe level is - 15dB, the worst peak sidelobe level is - 14.5dB, and the corresponding aperture size of sparse array is 22 and 26, respectively.
