基于脉冲幅值序列算法的抗红外干扰方法研究

摘要

用红外干扰弹诱使导弹偏离真实目标依然是使用最广的干扰方法，当前使用的红外干扰弹的运行轨迹和红外辐射特征与目标非常类似，对常用的几种抗干扰算法构成了很大的挑战。针对脉冲幅值序列算法做了深入细致的研究，对功率谱分析法、传统正交小波变换法、时域分析法等多种方法进行了仿真和分析，并介绍了一种新方法--多尺度的离散平稳小波变换法，能够有效分辨开目标信号与红外干扰弹信号，改善了红外探测器的抗干扰能力和目标识别能力。%Using infrared decoy to lure missile from the real target is still the most widely used method of interference.The trajectories and infrared radiation characteristics of the current IR decoy and the target are very similar, so several kinds of commonly used antijamming algorithm face a big challenge. A detailed research on the impulse value sequence algorithm is proposed in this paper.Power spectrum analysis method, traditional orthogonal wavelet-transform method, time-frequency analysis method and other methods are simulated and analyzed, and a new method named multiscale discrete stationary wavelet transform method is introduced. It effectively distinguishes the target signal from the IR decoy signal, improving the ability of anti-jamming and target recognition of IR detector.
