Cross-eye gain distribution of multiple-element retrodirective cross-eye jamming

摘要

The total cross-eye gain of multiple-element retrodirective cross-eye jamming (MRCJ) in the presence of the platform skin return is a distribution rather than a constant value, due to the random variation in the phase of the skin return. Although the median value of the total cross-eye gain distribution had been analyzed in previous studies, the extreme values providing useful indications of the upper and lower bounds of the total cross-eye gain have not been analyzed until now. In this paper, the cumulative distribution function and the extreme values of the total cross-eye gain of MRCJ are derived. The angular error induced in threat monopulse radar as a figure of merit is used to analyze the performance of MRCJ system. Simulation results demonstrate the variation of the angular error and discuss the proper value of jamming-to-signal ratio (JSR) making the MRCJ system more effective in consideration of the whole distribution of the total cross-eye gain.
