To improve the anti sweep jamming performance of the Chaotic Codes Phase Modulation and Linear Frequency Modulation (CCPM-LFM) hybrid modulation radio fuze, the response of the CCPM-LFM fuze under sweep jamming was analysed, and an anti jamming method based on harmonic coefficient amplitude average was proposed. This method was based on the ranging principle of Instantaneous Correlation Harmonic Demodulation (ICHD), and the harmonic envelope extraction was realized by Fast Fourier Transform (FFT) algorithm. By averaging the harmonic coefficient amplitudes obtained from multiple times of FFT, this method took the advantage of the random and statistical characteristics of the chaotic codes, and the jamming was effectively suppressed. Theoretical and simulation results show that the method can effectively suppress the sweep jamming without affecting the ranging resolution of the fuze.
