Platform Skin Return and Retrodirective Cross-Eye Jamming

Abstract

The effect of platform skin return on retrodirective cross-eye jamming is analysed, allowing the parameters of a cross-eye jammer in the presence of skin return to be determined. The inherently unknown phase of the platform skin return is accounted for, and the effect of variations in jammer-to-signal ratio (JSR) is investigated. The widely-held, though unsubstantiated, view that a JSR of 20 dB is required for effective cross-eye jamming is found to be reasonable, though conservative.
