Abstract

With the continuous rise of broadband radar in recent years, the information acquisition of space targets has gradually expanded from the original RCS, orbit, one-dimensional range profile and other one-dimensional information to twodimensional image information. The traditional recognition and matching of space targets based on orbit information plays an important role in certain scenes, but for some orbit change targets, especially for orbit change outside the detectable range, To a large extent, it is necessary to recognize according to the shape of the target, and high-resolution ISAR images are helpful to recognize and judge the orbit changing target. This paper presents a spatial target recognition method of ISAR Image Based on principal component analysis (PCA). The recognition effects of training and testing in different imaging time periods are studied successively, and compared under different recognition methods. Based on the constructed target database, the principal component analysis method has a better recognition effect.
