The authors developed a system for sampling the radar echo signals in high frequencies by A/D conversion of the receiving signals. Using this system, we analyzed the two-dimensional distribution of radar echoes of a point target such as a small FRP boat and report the following results. 1. The size of the images by the radial-scanning (azimuth and distance) becomes larger than the theoretical value as the radar sensitivity goes up. The image size by sensitivity decreases characteristically to the change of distance. 2. In high sensitivity, the image by the radial-scanning is as twice large as the theoretical image determined so far, at a close distance around 1,000 meters. 3. The width to length ratio of the image size on the radar screen is almost identical to the value evaluated as the Echo paint of the point target.
