摘要: 在介紹偽碼體制引信的工作原理和噪聲調(diào)頻干擾原理的基礎(chǔ)上，詳細推導(dǎo)了偽碼調(diào)相引信和偽碼調(diào)相與PAM復(fù)合引信在噪聲調(diào)頻干擾環(huán)境下的總信干比增益，并仿真實現(xiàn)了偽碼體制引信的工作過程，得出的仿真總信干比增益與理論的推導(dǎo)值接近。理論和仿真結(jié)果及輸出的相關(guān)值證明，一般而言，偽碼體制引信具有較強的抗噪聲調(diào)頻干擾能力。

Abstract: The principle of pseudo-random phase modulation fuze, pseudo-random phase modulation and Pulse Amplitude Modulation (PAM) combined fuze, and noise FM jamming are introduced in brief. On this basis, the Signal to Jamming Ratio (SJR) gains of the two fuzes in noise FM jamming environment are deduced in detail. Then, the working process of the two fuzes is simulated, whose results are close to the theory. These results and the output of correlation prove that the pseudo-random code fuzes have strong performances of anti-noise FM jamming generally. -
