摘要
根据回波信号与参考信号互WVD分布的特征,提出了一种基于互WVD分布的目标回波参量快速估计方法。通过与时域相关法相结合,既提高了运算速度,又获得了良好的估计性能,因而更具工程实用价值。仿真实验证明了该方法的有效性。
According to the features of cross Wigner-Ville distribution(XWVD)between echoes and reference signal,a fast estimation method of parameters of echoes based on XWVD is presented.Com-bined with the time domain correlation,it greatly reduced the computation load while keeping good es-timation performance.Simulation results show the effectiveness of the method.[
