Motion distortion compensation methods for navigation radar images
Aiming at the image aberration problem caused by the motion of radar carrier ship,the causes of target ima-ging 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 compensa-tion.The algorithm includes three parts:target detection,motion compensation and target image correction.Through the ac-tual 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 abil-ity of surface ships.
