ABSTRACT:
A radar apparatus and a radar signal processing method can prevent misdetection even in the case of targets running side by side without an azimuth angle error being varied in accordance with the velocities of the targets. An antenna direction control part controls the direction of an antenna so as to vary the directions of radar beams at the time of observation in up phases and at the time of observation in down phases. An azimuth angle calculation section of a signal processing part calculates azimuth angles in up and down phases, and an azimuth angle determination section of the signal processing part selects an output content of observation data concerning a target to be detected from the amplitude of a difference between the azimuth angles in up and down phase.
