| 摘 要： | 在介绍伪码体制引信的工作原理和噪声调频干扰原理的基础上，详细推导了伪码调相引信和伪码调相与PAM复合引信在噪声调频干扰环境下的总信干比增益，并仿真实现了伪码体制引信的工作过程，得出的仿真总信干比增益与理论的推导值接近。理论和仿真结果及输出的相关值证明，一般而言，伪码体制引信具有较强的抗噪声调频干扰能力。

| 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. |
