The traditional LFM (Linear Frequency Modulation) signal is easy to be intercepted and jammed because of the simple waveform. This paper proposes one kind of FM-PM co-modulated pulse compression signal obtained by combining in-pulse linear frequency modulation and sub-pulse phase modulation. Through the analysis and MATLAB simulation of anti-jamming, it has been proved that this co-modulated signal has the advantages of higher ability for anti-interception and anti-jamming, and the co-modulated signal can be easy generated and processed.
