Cross-eye jamming of monopulse radar

Radar seeking missiles present a serious threat towards ships and aircraft. In cross-eye jamming a missile seeker is deflected by signals from two onboard antennas transmitting out of phase with signals of nearly equal strength. The limits on cross-eye performance imposed by scattering have been studied when scattering takes place far from the propagation path. It will be shown that a digital cross-eye system with several antenna units can be seriously affected by scattering from sea waves and terrain.
