<p><P>PROBLEM TO BE SOLVED: To solve a problem wherein the presence of a target is recognized in a direction different from a target direction to track not the target but a clutter, to bring erroneous locking, when receiving a signal of a reflected wave from the target transmitted through the clutter such as a sea surface and a ground surface, in the tracking of detecting a target signal by transmitting a radio wave toward the target and by receiving the signal reflected directly from the target, in a conventional guide device. <P>SOLUTION: A system of the present invention can obtain two kinds of target-directional and clutter-directional reception signals, by transmitting the radio wave while switching angles along a target direction and a clutter direction, although the radio wave is transmitted only along the target direction in the prior art, the clutter is removed by comparing the two kinds of reception signals, and the target is tracked at an accurate angle without being locked erroneously to the clutter. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
