摘要
首先分析了双平衡调制器伪随机码调制法的工作原理,在此基础上提出了一种新的复合调制引信—伪码调相与正弦调幅复合调制引信。详细阐述了其实现原理,推导了各个阶段的信号形式,最后通过分析复合调制引信的特性,证明这种复合调制引信具有优越的性能,尤其是具有极强的抗干扰能力。
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.
