PURPOSE:To improve a detection rate for a target except an electro counter measure device, by a method wherein the directon of an elevation angle beam is assigned. CONSTITUTION:An assigned position, an assigned beam, and an assigned size for position and bearing, which are generated by means of a control indication unit 11, are transmitted to a signal processing unit 12, and a blank range of a beam elevation angle determined by a processing circuit 3 is stored in a direction reference memory 4. A receiving signal (a) from a radar is outputted to a blank circuit 5, and after a part corresponding to the details of the memory 4 is blanked, it is transmitted to a video indication circuit 6. As a result, jamming wave for the receiving wave is eliminated, and a detection of a target, which is different in its elevation angle even if it is in the same direction as that of a jamming device, can be performed. |
