摘要
运动目标的检测和成像是合成孔径雷达的难题之一,但又具有很强的实际意义,本文将ADPCA技术同MP法结合起来用于运动目标的检测和成像,其中将ADPCA技术用于运动目标的检测.MP法则解决了运动目标参数提取这一难点.计算机模拟的结果验证了该两算法的可行性,本文最后给出了可行的运动目标成像框图.
Moving targers detection and imaging is one of the difficulty points in SARProcessing. Actually if is very useflu Combined with ADPCA and MP, this paper puts the two methods in moving targets detection and imaging. ADPCA is used in moving targets detection, and MP is used to obtain the parameters of moving targets which was used to be very difficulty The simulation results show the reliability of the two methods. At the end of this paper, we give out the usable and reliablle diagram for moving targets imaging.
