A Study on Mono-pulse Radar Coherent Jamming

Mono-pulse radar angle tracking system is introduced. The principle of coherent jamming to mono-pulse radar is ana- lyzed. The jamming analysis model under the joint action of the coherent jamming and the target echoes and the calculation method of the optimal jamming-to-signal ratio are presented. At last,the jamming effects have been obtained by computer simulating under the condition of different jamming parameters,and the simulation result shows the principal factors affecting angle measurement performance and its action rules.
