摘要 讨论了用窄带接收机测量宽带噪声干扰信号到达时差时 ,干扰源、转发站和接收机的相对运动对时差测量最大似然估计和直接相关估计精度的影响 ,并给出了一种适用于运动干扰源的最大似然估计器的实现方法。 The time delay of wide band signals received by narrow band receivers is studied, focusing on the effect of relative motion between jammer and receivers. The performances of maximum likelihood estimation (MLE) and direct cross correlation estimation (DCCE) are given. A ML estimator for moving jammer is presented.
