Abstract

Abstract:

Cross-eye jamming is an effective angle deception jamming against terminal guidance radar, making the missiles unable to track and strike targets effectively. For this kind of main lobe interference, the existing terminal guidance radar lacks effective countermeasures. To this end, this paper proposes an anti-cross-eye jamming method based on monopulse radar 3-D imaging. The method first performs high-resolution processing on the three-channel signals of monopulse radar in the range and Doppler dimensions. By measuring the azimuth angles and pitch angles of each resolution unit, the 3-D image of the target is obtained by combining the distance information. The three-dimensional image is then used to set an appropriate threshold using the agglomeration effect of the target to eliminate the singular points outside the target size caused by cross-eye interference, so as to obtain the angle measurement result after the interference countermeasure, which ensures the effective tracking of the target by the missile. The simulation results prove the effectiveness of this method to suppress the main lobe angle interference.

Key words: amplitude-comparison monopulse, cross-eye jamming, main-lobe jamming suppression, 3-D imaging
