In this paper,a new feature matching algorithm based on the geometric position relationship of strong scatter-ing points is proposed for scene location after radar imaging.First,strong scattering points on an image are extracted based on grayscale characteristics,and then the candidate points are connected to form an irregular polygon.Matching location is achieved by analyzing the geometric position relationship between the vertices of the polygon.The results of a simulation test using measured data show that the proposed method has small computational complexity,high matching accuracy,high reliability,and high robustness.It is a radar image matching method with high engineering application value.
