Abstract

The effect of LFM jamming on PRPPM-PRBC compound systemic fuze is analyzed. It is found that the correlation curve is deteriorated when LFM jamming power is larger than the anti-jamming limit of the fuze system. It is necessary to excise LFM jamming before correlation. Through the analysis of fractional Fourier transform result of LFM signal, the method of excising LFM jamming in fractal rank domain is put forward. Through simulation analysis, it is found that the method proposed can effectively excise the LFM interference and ameliorate the correlation curve.
