本方法对目标回波信号采用了相干视频模拟法,在视频上模拟目标回波的多普勒频率。
In the method, the target reflected signal is generated by the way of coherent video simulation and the Doppler frequency of target is simulated on video.
提出了一种先对回波信号进行多普勒补偿后再进行相干积累的方法。
The method in which coherent accumulation is carried out after the echo is compensated by a Doppler frequency shift is introduced.
