摘要
Abstract
Radar reconnaissance is to detect enemy radar emitter signals by passive reconnaissance equipment. When the energy of enemy radar signals reach interception sensitivity,it can be thought that signal is unintercepted. However,in the modern battlefield,electromagnetic environment is complex and the enemy radar signals are always covered by noise or interference signals,so the result is false dismissal rate improved. In view of the above problems,a radar signals detection method based on stochastic resonance theory is proposed. The detection problem of signal is covered by excessive noise can be solved. Apply the detection method to front-end intercept in radar warning receiver system,it can reduce the false dismissal rate of system and ensure the system robustness. Simulation results verify the detection method feasibility.关键词
