Abstract
While received data is stored into a video memory through coordinate conversion, the level of image data is gradually reduced simultaneously with this, by which the image of a target is discriminately displayed readily from among a clutter even without performing adjustment which would conventionally be involved. The radar apparatus is composed of a video memory for successively converting received data from polar to rectangular coordinates along with sweep rotation and storing the data, a FIRST detector for detecting a FIRST so that data write by the coordinate conversion is effected only at a time of FIRST detection, and a subtraction data generator for subtracting a constant value from pixel data of a area designated by a subtraction area designator on the video memory during a period other than FIRSTs.
