Abstract
Cross-eye jamming is a technique to counter monopulse radar. The impact of the amplitude-phase error on the jamming performance is one of the key problems for cross-eye jamming. The tolerance of amplitude-phase error for cross-eye jamming has been analyzed by deterministic analysis. However, the amplitude-phase errors of a practical jammer are commonly stochastic variables due to the variation of working conditions. In this article, the probabilistic analysis of the amplitude-phase error tolerance for cross-eye jamming is studied. By demonstrating that the contours of cross-eye gain can be approximate to a set of ellipses, the probability distributions of cross-eye gain and angle factor are derived, based on the assumption that the amplitude-phase errors of cross-eye jammer are Gaussian distributed. The article presents the instructions to determine the required standard deviation of the amplitude-phase error to produce a specific confidence level of cross-eye jamming performance metric.
