ABSTRACT:
A radar apparatus in which an interpolated sweep between adjacent real sweeps is formed irrespective of an interval between the real sweeps, and image data corresponding to one cycle of sweeping can be certainly updated. A sweep azimuth generator (12) generates and outputs an azimuth of sweep interpolated between a current and previous real sweep azimuth based on the current and previous real sweep azimuths, to a draw address generator (7). A sweep data generator (11) performs linear interpolation based on solitariness removed data of current real sweep data read from a sweep memory (4), and the previous solitariness removed real sweep data stored therein to generate and output interpolated sweep data to an image memory (8). The image memory (8) stores the solitariness removed real sweep data or the interpolated sweep data based on the real and interpolated sweep azimuths from the draw address generator (7), and outputs them to a display (9).
