摘要
Abstract
A kind of emission signal is designed for intermittent sampling interference,and the slope of the signal is alternately changed in a pulse width.After the short-time Fourier transform of the target echo and the intermittent sampling interference,the positive and negative frequency energy distribution characteristics of the extracted spectrum is matched with the transmitted signal,and the interference is discriminated.When the interference is not present,the normal pulse compression can be carried out.When the interference exists,the interference component in the matched filtering result can be filtered out by a time domain filter.The results of computer simulation show that the algorithm can maintain a high recognition rate under reasonable signal-to-noise ratio and dry signal ratio,and can effectively suppress intermittent sampling interference.关键词
