摘要: 首先分析了雙平衡調(diào)制器偽隨機(jī)碼調(diào)制法的工作原理,在此基礎(chǔ)上提出了一種新的復(fù)合調(diào)制引信-偽碼調(diào)相與正弦調(diào)幅復(fù)合調(diào)制引信.詳細(xì)闡述了其實(shí)現(xiàn)原理,推導(dǎo)了各個(gè)階段的信號(hào)形式,最后通過分析復(fù)合調(diào)制引信的特性,證明這種復(fù)合調(diào)制引信具有優(yōu)越的性能,尤其是具有極強(qiáng)的抗干擾能力.

Abstract: 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 -
