In AMTI radar the platform motion causes ground clutter appearinga Doppler shift in frequency.Spreading of spectrum makes the return signal fromsucessive radar repeat period to exhibit a phase advance.This platform motion effectsare analyzed and a compensating method by producing a proper correction signaladaptively is presented in this paper.This compensation is not limited to twopulse-return,it is applicable to many pulse-return.This method can provideconvenience for MTI processing.The first cancelling effects with compensation andwithout compensation are given as well.

AMTI 雷达中,由于平台运动,地面固定杂波平均多普勒频率平移及杂波谱展宽,造成两相邻脉冲回波间产生一相位超前。本文对这种平台运动效应进行了分析,提出了一种采用自适应方法产生校正信号,对回波平台运动效应进行了补偿。这种补偿不局限于每次两个脉冲之间,而可适用于多个脉冲,从而为 MTI 处理提供了方便。还获得了有、无补偿的一次对消处理结果。

The authors advance an adaptive cancelling system, whichhas evident cancelling effect on ASK signal noise produced by intenseelectricity.On the basis of analysing the property of the main parts ofcancelling system, balanced adaptive signal separator and adaptive waverecognition detector, a hardware system is developed. The test showsthe system with a clear effect on cancelling noise.

作者提出一种自适应消噪系统,对受强电干扰(宽带平稳过程)的ASK混噪信号有明显消噪效果。在分析消噪系统主要部件(平衡式自适应信号分离器及自适应波形识别检测器)性能的基础上,研制出硬件系统。经测试表明,该系统消噪效果明显。

The operating principle of a noise-cancelling system is introduced in this paper, and the system scheme of the active noise-cancelling headphone in feedback mode is described in detail. By the circuit simulating debugging and testing, the noise-cancelling effects of the headphone are proved.Atast,some improvements are proposed.
