The jamming effect of the suppressing noise frequency modulation(NFM) jamming on the pseudo-ran-dom code phase modulation and sine FM( PRCPM-SFM) combined pulse train fuze was investigated.Firstly, an analy-sis model of the jamming effect for the combined fuze was set up.Secondly, the overall signal to jamming ratio ( SJR) gain of the correlator output signal was reduced under the NFM jamming.Thirdly, the valuation method of the sup-pressing NFM jamming effect was derived in terms of the overall SJR gain.Finally, the factors influencing the jamming effect were discussed.The result shows that the jamming effect of PRCPM-SFM combined pulse train fuze under the suppressing NFM jamming can be improved effectively by utilizing these factors reasonably.
