<p>PROBLEM TO BE SOLVED: To make a target unable to specify a place of a radar apparatus body by setting an antenna for directly transmitting radio waves to the target at a repeater and making the target specify only a position of the radio wave repeater. SOLUTION: When a radar transceiver 1 starts transmitting, a unidirectional antenna 7 irradiates a primary transmission wave 9. When the transmission wave 9 reaches a unidirectional antenna 8, a phased array antenna 2 emits a transmission wave 3. A transmission reception direction control device 6 changes a direction of the transmission wave 3. When the radar transceiver 1 detects a detection wave 5 reflected by a target 4, the direction control device 6 fixes a transmission reception direction to a direction of the target 4. The transceiver 1 obtains information on a position of the target from a reception wave 10 which is the wave 5 passing through a repeater T. A processor 12 sends to the transceiver 1 a correction command for the position of the target 4 on the basis of a position of the transceiver 1 stored in a memory device 11 and a relative position of the antenna 2, whereby a relative position of the transceiver 1 and the target 4 is obtained.</p> |
