摘要
微弱多目标检测中,高速运动目标的跨距离单元走动会影响长时间相参积累的效果,论文提出了在低信噪比情况下通过Keystone变换校正多目标的跨距离单元走动,对所有脉冲相参积累达到提高信噪比的目的,仿真实验结果验证了该方法的有效性。
In weak multiple targets detection,migration through range cells（MTRC）of high-speed targets would affect the performance of long time coherent integration.In this paper,a novel motion compensation method based on Keystone transform is presented,which can correct range migration.The SNR is improved through coherently accumulating all pulses.Performance of simulations verifies the value of the proposed algorithm.
