The present invention relates to a multi-beam type rear and side directional radar which can detect a plurality of rear and side regions (BSD, LCA, RCTA and RCW) using multi beam by digital beam forming signal processing method especially, in a vehicle radar. The multi-beam type rear and side directional radar includes: a transmitting antenna for transmitting a transmission signal for detecting a target; receiving antenna for receiving a receiving signal reflected from the target; a multiplexer for multiplexing and outputting receiving signals received through the receiving antennas; an AD converter for an analog receiving signal outputted from the multiplexer into a digital receiving signal; an a digital beam forming part for forming a number of receiving beams to detect BSD area, LCA area, RCTA area and RCW area by multiplying the digital receiving signal by DBF weighted value (Wi).
