基于双门限法的激光引信抗云雾干扰技术研究

Research on Anti-Cloud and Fog Interference Technology of Laser Fuze Based on Double Threshold Method

提出了双门限判别方法,即在传统信号幅度门限的基础上增设增速门限。利用MATLAB软件进行仿真,由于双门限法降低了引信的虚警概率,能够较好的排除云雾散射信号的干扰,完成对目标信号的识别,效果明显优于单一的幅度门限判别。

This paper presented a dual threshold discrimination method by comparing the characteristics of cloud backscattered signals and real target echo signals.Based on the threshold,a speed increase threshold was added for discrimination.Using MATLAB software to simulate,because that the double-threshold method reduces the false alarm probability of the fuze,and can better eliminate the interference of the cloud scattering signal and complete the recognition of the target signal.The effect is obviously better than a single amplitude threshold discrimination.
