| 摘 要： | 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。

| Abstract: | 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. |
