Automobile Anti-collision Millimeter-Wave Radar Signal Processing

Abstract

Distance and velocity measurements are primary mission of radar in automobile anti-collision application. The signal processing procedure is established according to the principle of distance and velocity measurement. Signal processing platform are constructed based on two FIFOs for data sampling and 32bits DSP. By analyzing the relationship between safe distance and relative velocity in highway the measurement indexes are provided. According to above the signal processing technique indexes are established. System working parameters are restricted each other, to resolve this problem the radar system working parameters formulating method and steps are provided based on 10GHz carrier frequency. The time-frequency performance of 1024 FFT is analyzed and main algorithms of signal processing are accomplished.
