<p><P>PROBLEM TO BE SOLVED: To solve problems wherein the capacity of hardware increases when a number of reception antennas are set and a calculation processing load increases since a video signal is simultaneously received for analog/digital conversion processing at a signal processing section in a moving target detector for transmitting/receiving radar waves by using a plurality of reception antennas, forming a Doppler filter on a two-dimensional space of frequencies and time, and detecting a low-speed moving target, such as a vehicle and a ship. <P>SOLUTION: In the moving target detector, the need for providing a reception section 5 for each reception antenna 3 is eliminated by arranging partial reception antennas 3 in a plurality of reception antennas 3 at an interval differing from that of other reception antennas 3 and switching the reception antennas 3 to other reception antennas 3 via a switcher for making the reception section 5 common. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
