Abstract

Among the common vehicle-mounted radars, vehicle-mounted millimeter-wave radar is an important component of vehicle-mounted sensors. The core of the vehicle-mounted millimeter-wave radar system is its signal processing module. Signal processing algorithms based on digital signal processing technology have extremely important and far-reaching significance for the research and development of vehicle-mounted millimeter-wave radar. This paper analyzes the overall structure and basic working principle of the vehicle-mounted millimeter-wave radar system, designs a signal processing algorithm structure scheme of "Beat - Beamforming - Fourier spectrum analysis -MTD", and studies three key algorithms involved in FMCW radar signal processing: CFAR detection, MTD technology, and MTD velocity pairing method.
