Abstract

PURPOSE:To detect a jamming direction with respect to all of frequencies within a radar band, by mounting a jamming wave analyzing circuit for analyzing the rough azimuth and frequency of a jamming signal and a jamming direction detecting circuit for determining the beam number of the jamming signal direction. CONSTITUTION:An auxiliary antenna 21 receives the frequency and azimuth data of a jamming signal having fan beam wide within a vertical plane but narrow within a horizontal plane, and the frequency and azimuth data are analyzed by a jamming wave analyzing circuit 22. A reference signal generating circuit 19 sets a transmission pulse repeating cycle to one wherein a jamming observing time is added to the time necessary for the reception of a usual target signal and generates local oscillation frequency for making jamming signal frequency synchronous to said time. A jamming direction detecting circuit 20 determines the beam number showing the max. value in the jamming signal output of each beam within the vertical plane. By this constitution, the observation of a jamming signal in a band different from target searching frequency becomes possible and elevation can be also measured without limiting directional searching to the measurement of an azimuth direction.
