<p>PROBLEM TO BE SOLVED: To provide a device for receiving a radiated radar wave, capable of intensifying it and reradiating it in the direction of its radiation, and capable of detecting the direction of the radiation. SOLUTION: A retrodirective array is formed by using a plurality of unidirectional antenna elements disposed on a circumference. On this occasion, an amplifier is put in a reradiation system to intensify electric power for reradiation. The direction of the radiation is detected by signal processing from the directional characteristic of the used antenna elements and the positions where they are disposed.</p> |
