Abstract

Aiming at the problem of insufficient analysis of the influence of self-defense jamming on the radar measurement to determine the target position, the mean and standard deviation of the conversion error under different jamming are derived. The angle and distance measurement errors of the radar to the target under different jamming are analyzed, and the coordinate conversion equation is used to derive the mean and standard deviation of the conversion error under different jamming. The simulation results show that the self-defense noise jamming makes the conversion error more random and the error standard deviation increases; the self-defense deception jamming makes the coordinate conversion produce a fixed error. It shows that under the influence of different self-defense jamming, the positioning of the target by the radar produces different fixed error and random error, the performance of the radar is greatly affected. The target penetration success probability is guaranteed.
