基于LabVIEW 的伪码调相脉冲引信抗GWN干扰研究

为解决当前伪码调相脉冲引信抗干扰研究资料相对匮乏的问题，研究伪码调相脉冲引信在高斯白噪声 (white gaussian Nnoise)干扰下的抗干扰性能。在分析伪码调相脉冲引信工作原理和抗干扰原理的基础上，利用 LabVIEW 进行模块化编程方法，得到在不同码元宽度和伪码长度下伪码调相脉冲引信相关解调信号的抗GWN 干扰 仿真结果。结果表明：伪码调相脉冲引信抗干扰性能受码元宽度和伪码长度的影响，码元宽度越窄，伪码长度越长， 抗干扰效果越好。

Research on Anti-GWN Interference of PN Code and Phase Modulation Fuse Pulse Based on LabVIEW

In view of the lack of research on the anti-interference performance of PN code and pulse-Doppler combined fuse, the anti-interference performance of this fuse under white Gaussian noise (GWN) condition is studied. Based on analyzing of the working principle and anti-interference principle of this fuse and using the modular programming method in LabVIEW, the anti-GWN interference simulation results of PN code and pulse-Doppler combined fuse related demodulated signals with different symbol width and PN code length are obtained. The results show that the anti-interference of the PN code and pulse-Doppler combined fuse is affected by the symbol width and the PN code length. The narrower the symbol width, the longer the PN code length, the better the anti-interference effect.
