<p>PROBLEM TO BE SOLVED: To detect a target such as another aircraft without arranging a radar antenna or a transmitter/receiver or the like by detecting the target based on a correlative processing result which is executed concerning a transmission monitor signal taken-out from a transmitter and the reflection wave of a prescribed communication wave, which is reflected by the target. SOLUTION: The transmission signal outputted from the transmitter 7 is taken-out to a correlative processing unit 13 as the transmission monitor signal and a correlative processing with a reception signal outputted from a receiver 10 through the use of the transmission monitor signal is executed so that a signal where a signal strength is concentrated in terms of time is obtained. Then a direction or a distance or the like with respect to the target 4 are detected based on the signal after the correlative processing. That is, the correlative processing unit 13 respectively inputs the transmission monitor signal taken- out from the transmitter 7 and the reception signal outputted from the receiver 10 so that the signal in the concentrated form in terms of time can be obtained.</p> |
