基于多域积累的弱信号检测方法
A technology for weak signal detection based on multi-domain accumulation
摘要
Abstract
Aiming at the demand for increased reconnaissance distance in complex electromagnetic environ-ments,a weak signal detection method based on multi-domain accumulation is proposed.This method comprehen-sively utilizes channelization processing,cyclic autocorrelation,and non-coherent accumulation to conduct multi-domain processing of signals,achieving multi-domain signal energy accumulation and thereby enhancing the signal detection gain.Simulations are also performed to verify the effectiveness of this method.The simulation results show that,under the condition of an input signal noise ratio(SNR)of-17 dB,the signal detection probabili-ty of the method can reach 93%,even with a higher detection sensitivity.关键词
