%X The principle of Discrete Evolutionary Transform(DET) and Discrete Evolutionary Hough Transform(DEHT) are introduced. The method of excising multi-component FM interference for pseudo-random coded fuze system based on DEHT is analyzed in detail. The instantaneous phase of interference is firstly estimated with DEHT and the estimated phase error is decreased through recursive correcting. An adaptive time-varying filter based on the estimated instantaneous phase is set up to excise the interference one by one. The correlator output in different ISR situations is simulated. It is found by simulation that the method can effectively excise the interference and improve the correlator output.
