1. A radar apparatus comprising:

  • a coordinate converter that converts detected data at each sample point obtained in a polar coordinate system into a rectangular coordinate system;

    a detected image data generator that generates a pixel of detected image data based on each point of the converted detected data;

    an image memory that stores the generated pixels of detected image data;

    a data shifter that shifts detected image data input from the detected image data generator with predetermined timing and outputs the shifted detected image data; and

    an azimuth direction detected image data corrector that compares generated pixels of detected image data of a current sweep with shifted detected image data of a previous sweep at the same position in a sweep distance direction, and outputs a maximum value of pieces of detected image data as detected image data of the current sweep.
