Abstract: Cross-eye jamming is considered to be one of the most effective methods for monopulse radar. Based on the radar equation, a two point source retrodirective cross-eye mathematical model under isolated platform echoes is established, and a general formula of indicate angle is derived. The influences of the parameters such as the distance between the jammer and the radar, the distance between the transmitting antenna, and the rotation angle of the jamming platform on the angle deception effect are studied. A simulation model of monopulse radar receiver is established in reference to the processing flow of the angle obtained by the monopulse radar. The correctness and limitation of the mathematical model are analyzed. The results show that the closer the monopulse radar is to the central line of the jammer, the larger the distance between the two transmitting antennas, and the smaller the distance between the monopulse radar and the jammer, the better the effect of angle deception. The deception angle of the monopulse radar increases exponentially with the decrease of the range. The maximal difference between the monopulse radar angle calculated by the mathematical model and by the simulation model increases exponentially with the increase of the angle between the jammer antenna and the center of radar antenna. This paper is implicational for designing cross-eye jammer engineering.
