PURPOSE:To contrive so that a target other than a jamming unit may be detected by specifying the frequency of a blank with regard to a radar device having more than two transmission frequencies. CONSTITUTION:Centering around a location specified by a location specification circuit 1, frequency blank setting conditions for a frequency specified by a frequency specification circuit 7 are memorized at an address for which a detection reference memory 4 is set by a processing circuit 3 in a size specified by a size specification circuit 2. The part of a signal a received from a radar that is memorized by the detection reference memory is blanked by a blank circuit 5 and then is displayed by a video display circuit 6. Under this constitution, the location of a jamming unit and the frequency of a jamming electric wave are caused to be memorized into the detection reference memory 4 by means of the location specification circuit 1, size specification circuit 2 and frequency specification circuit 7. As a result, it is possible to eliminate a jamming wave by means of the blank circuit 5 and detect a target other than the jamming unit. |
