Abstract

PURPOSE: To eliminate the omission of a minute target image and to reduce a memory capacity, by detecting a peak value of a reception signal and by writing this peak value in a scan converter in an image memory type target display device of a radar or the like.
CONSTITUTION: A signal reflected by a target is amplified by a receiver unit 2 and inputted to an A/D converter unit 3. The reception signal inputted to the A/D converter unit 3 is sampled wit a higher sampling frequency than a sampling frequency for writing in an image memory by a high-frequency sampling unit, and the maximum value is determined from values obtained from a sampling. This maximum value data signal 3001 is written in a scan converter unit 4 as image data for each image unit at every sampling for writing. A signal 4001 read out of the converter unit 4 is outputted to and displayed in a display unit 5.
