| 摘 要： | 针对强噪声背景下雷达信号处理困难的问题,提出一种基于Lyapunov指数的雷达信号处理算法,建立相应的Duffing系统仿真模型,利用Lyapunov指数求解该模型由混沌态跃变为周期态的阈值,提取出回波信号频率,根据其多普勒频移计算出导弹与目标间的相对速度。仿真结果表明,该系统的最低检测门限可达到-70dB以下。

| Abstract: | In view of the problem of radar signal processing under the strong noise back- ground, a radar signal processing algorithm based on Lyapunov exponents is proposed. Then the corresponding Duffing simulation model is created and the model threshold for the state from chaos to cycle is solved by using the Lyapunov exponents. Based on the threshold, the echo signal frequency is extracted. Then according to the Doppler shift, the relative speed between the missile and the target is calculated. |
