对相位可导信号的预测进行了研究,提出一种较高精度的快速信号预测方法,利用这种方法有可能实现目标的有源隐身以及对线性调频信号产生前拖假目标。仿真结果证实了本方法可以大幅度减小目标回波的幅度,以及可以对线性调频的脉压信号产生前拖的假目标。
The prediction of phase-guided signal is studied, and a new method of fast signal prediction with higher accuracy is proposed. It is possible to realize the target’s active stealth and to pre-delay the LFM signal. The simulation results show that this method can significantly reduce the amplitude of the target echo and the pre-dragged false target on the chirp signal of chirp.
