【摘要】 合成孔径雷达(SAR)是一种高分辨成像雷达,但对运动目标的成像经常会出现模糊和方位向偏移。本文对文献[1]提到的利用单脉冲SAR实现地面动目标检测(GMTI)技术进行简单的介绍,该方法利用单脉冲系统接收的和/差通道的聚焦数据对成像场景中的动目标进行检测,并且进行方位向偏移校正,以及准确测得各个动目标的径向速度分量。更多还原

【Abstract】 Synthetic aperture radar(SAR) is a high resolution imaging radar while image of moving objects are often smeared and displaced in azimuth.Ground moving target indication(GMTI) with a monopulse SAR mentioned in is introduced in the paper.The method makes it possible to detect moving target in imaging scene,correct the azimuth displacement and measure an accurate individual radial velocity component of moving targets with focused data from sum and difference monopulse channels received by monopulse system.更多还原
