Detection of slow moving targets using automotive radar sensors

Detection of (slow-moving) pedestrians in an urban environment is a highly sophisticated task. This paper presents a signal processing technique suitable for frequency modulated continuous wave (FMCW) radar sensors using chirp sequence modulation, allowing observation of slow-moving targets with high resolution capability in range and velocity. Velocity and range resolution can be improved through linear prediction without requiring higher bandwidth or longer measurement time. To verify the signal processing technique, measurement results are presented at the carrier frequency of 79 GHz.
