multibeam-type rear and side directional RADAR using MIMO signaling method

摘要

In the the present invention is a vehicle radar, in particular by using a multi-beam of a multiple beam approach lateral radar after that can detect a plurality of after lateral region (BSD, LCA, RCTW and RCW) as, and the M transmitting antennas for transmitting a transmission signal for detection of the target, and the N receive antennas for receiving the reflected received signal to the target, in-phase receive channel for the received signal received through an antenna and a multiplexer for output multiplexes each of the received signals of the received signal and the quadrature-phase receive channel, and the AD converter for converting the analog reception signal outputted from the multiplexer to a digital received signal, via a signal processing on the digital received signal second reception beam constituting the virtual array antenna pattern of M N dog aelrimeonteu, and covering the first receive beam which covers the side blind spot detection (BSD) area after over said virtual array antenna pattern, the lane change assistance (LCA) region , the first of three reception beam, and to be configured to include a digital signal processor to form a fourth receive beams covering a rear collision warning (RCW) zone characteristic invention which covers the rear parking assistance (RCTA) region ;
