Pseudo-random Code Phase-Modulation and Sine Amplitude-Modulation Combined Modulated Fuze

Firstly, the principle of pseudo-random code modulation based on double-balance modulator is analyzed. On this basis, a new combined modulated fuze-pseudo-random code phase-modulation and sine AM combined modulated fuze is advanced. And the principle of the combined modulated fuze is illustrated and the formula of signals in every aspects is deduced. Finally, by analyzing the performance of the combined modulated fuze, it is proved that the combined modulated fuze has advantageous performance, especially good characteristics of ECCM
