摘　　要：针对传统的侧视激光合成孔径雷达成像系统的缺点,研究了一种基于RMA的前视激光合成孔径雷达成像算法。首先研究了前视激光合成孔径雷达的组成原理,给出了系统的结构框图,分析了点目标的距离向和方位向多普勒历程,采用Matlab对成像结果进行了仿真,并对点目标的成像包络进行了详细仿真,结果表明,该算法可对雷达前视场景的目标进行有效成像。According to the shortcomings of the traditional side-view laser synthetic aperture radar （SAR） imaging system, an imaging algorithm of the front-view laser synthetic aperture radar was studied based on RMA. Firstly, the composition principles of the aperture radar are studied, and the system＇s diagram was given. Then the distance and azimuth Doppler history of point targets were analyzed, and the imaging results were simulated using Matlab. The imaging envelope of pointed targets was simulated in detail. The results show that the algorithm can image the target of radar front view scenes effectively.
