摘　　要：针对雷达载体船运动导致的图像畸变问题,分别分析高速直航运动和回转运动情况下目标成像畸变的原因;仿真分析相关参数对图像畸变带来的影响,并计算与运动参数相关的目标图像畸变补偿公式;提出目标雷达图像畸变补偿的应用算法。该算法包括目标检测、运动补偿和目标图像校正。通过湖上试验,采用目标图像畸变补偿后的目标定位精度指标按直航和回转运动分别提升了33.13%和47.38%,进而提升水面舰艇的感知能力。Aiming at the image aberration problem caused by the motion of radar carrier ship,the causes of target imaging aberration in the case of high-speed direct motion and slewing motion are analyzed respectively,quantitative simulation analyzes the influence of relevant parameters on image aberration,and calculates the target image aberration compensation formula related to the motion parameters,and proposes an application algorithm for target radar image aberration compensation.The algorithm includes three parts:target detection,motion compensation and target image correction.Through the actual test on the lake,the target localization accuracy index after using target image distortion compensation is improved by 33.13%and 47.38%according to the straight and slewing motions respectively,which in turn improves the perception ability of surface ships.
