Abstract:Retro-directive cross-eye 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 cross-eye jamming theory, the retro-directive cross-eye jamming technology under multiple elements scenario is analyzed. In the analysis procedure, the relationship between the retro-directive cross-eye jamming and retro-directive cross-eye gain is obtained by strict deriving. Then on this basis, the influence on retro-directive cross-eye 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 retro-directive cross-eye 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. © 2017, Editorial Office of Systems Engineering and Electronics.
