| 摘 要： | 雷达对抗侦察接收机在接收、截获脉冲信号的同时,也改变了脉冲信号的原始包络。这些改变不符合雷达辐射源识别的高精度要求。通过理论计算定性分析接收机对脉冲信号包络的不利影响,并提出利用非线性系统辨识理论中的最小二乘支持向量回归（LSSVR）算法获取接收机逆系统模型,以便恢复包络信息,最后通过仿真试验说明该方法的有效性。

| Abstract: | The envelope of pulse signal is changed when it is received or intercepted by radar electronic warfare reconnaissance receiver.The change influences the identification precision of radar emitter.The influence on pulse envelope is computed for qualitative analysis.Then the nonlinear system identification theory is used to solve the problem.The least squares support vector regression algorithm(LSSVR) gets the inverse system of the receiver in order to resume the changed envelope.Lastly,the experimentation res... |
