<p>PURPOSE:To display a moving target at low cost and in a simple manner by adding a simple pulse radar and thereby erasing a fixed target. CONSTITUTION:A moving target pick-up device added to a pulse radar device 15 is provided with an A/D converter 17 differentiating a video signal 7 to be delivered and converting an output thus obtained and the video signal 7 into digital signals respectively, with a digital instrument 18, with a display unit 20 displaying a distance to a target and the speed and the direction of advance thereof based on a moving target signal 19 delivered from the instrument 18, and with a pulse generator 21 for synchronizing the operation of the A/D converter 17 with a trigger pulse signal 12 from the pulse radar device 15. By using the video signal 7 and the trigger pulse signal 12, a signal in the range of a distance to be analyzed is synchronized with a system trigger pulse and digitized by the A/D converter 17, and is inputted into a computer 18.</p> |
