A Method of Reducing Angular Error in Tracking Noise Jammer with Mono-pulse Radar

摘要

When mono-pulse radar is disturbed by self-protecting noise jamming, angular tracking error signals can be extracted from noise jamming because jammer and echo from a target both come from the same direction. Based on the principle of angular tracking of mono-pulse radar and signal transmission characteristics when noise jamming passes a receiver, a few causes leading to angular errors are analysed and a method of reducing angular error in tracking noise jammer is put forward. A simulative test about angular error of active tracking and passive tracking are made on MATLAB platform, besides, influences of main parameters in the method on angular error of passive tracking are simulated. It is shown that angular error of passive tracking can be reduced by the method.
