Abstract:

Retrodirective crosseye jamming has caused lots of interests in recent years as a angle deception jamming technology against monopulse radar, in order to perfect the retro directive crosseye jamming theory, the retrodirective crosseye jamming technology under multiple elements scenario is analyzed. In the analysis procedure, the relationship between the retrodirective crosseye jamming and retrodirective crosseye gain is obtained by strict deriving. Then on this basis, the influence on retrodirective crosseye gain caused by the relative amplitude and phase error between jammers and target echo is researched under the multiple elements scenario, then the effect of those factors on retrodirective crosseye jamming performance is analyzed. The simulation results show that the relative amplitude and phase difference between the jammers become smaller, the relative amplitude of the target echo relative to the jamming signal becomes smaller, the retro-directive cross eye gain will be enhanced, and the jamming effect of the retro-directive cross-eye jamming technology will be enhanced.
