description The invention discloses a millimeter wave multi-antenna distance measurement system which comprises a multi-antenna transceiving structure and a window processing and distance angle combination extension algorithm corresponding to the multi-antenna transceiving structure. The multi-antenna transceiving structure comprises four transmitting antennas, eight receiving antennas and an electronic change-over switch. According to the system, an antenna is used for collecting data, distance dimension FFT is carried out, and primary windowing, primary interception, secondary windowing and secondary interception are sequentially achieved to obtain a processing window. And then secondary acquisition is carried out, the antenna is virtualized into one-transmitting 32-receiving, distance dimension FFT is carried out on the data, the data is intercepted and stored by using the window, then secondary distance dimension FFT and antenna dimension FFT are carried out in sequence, an angle range angle bin is obtained by combin
