| 摘 要： | 雷达辐射源识别是电子战系统的关键技术之一。分析了放大器的非线性效应,提出用谐波信号幅度之间的约束关系特征进行雷达辐射源识别的方法,针对谐波信号十分微弱的问题,提出采用谐波小波变换对信号进行重构、然后对重构的信号用最小二乘拟合进行幅度估计的方法,提高了幅度估计的精度。最后通过仿真验证了方法的准确性和有效性。

| Abstract: | Radar emitter identification is one of the key techniques of electronic warfare systems.The non-linear effect of the amplifier is analyzed and a method that uses the restriction relationship of the amplitude of the harmonic signal to identify the radar emitter is put forward.Aiming at the weakness of the harmonic signal,a method is put forward which firstly reconstructs the signal by harmonic wavelet and secondly uses the least square method fitting to estimate the amplitude of the reconstructed signal.The method enhances the precision of the amplitude estimate.Finally the simulation results validate the veracity and validity of the method. |
