帧间积累相邻回波不连通的慢速小目标航迹提取方法
A Track Initiation Method for Inter-Frame Accumulation of Adjacent Echo Disconnection Slow and Small Target
摘要
Abstract
Aiming at the problem that the traditional algorithms cannot initiate the track of adjacent accumulation echo disconnection slow and small target (SST),a track initiation method for SST based on Hough transform is proposed.The target echo is classified by introducing the length-width ratio F3 and duty ratio F2 of the minimum circumscribed rectangle of the target echo.In each classification domain,three parameters of the minimum circumscribed rectangle,the length-width ratio F3,the duty ratio F2,and the pixel value F1,are used as the weighting factors of Hough transform.These weighting factors are extracted by use of image marking technique.The SST trajectory in each classification domain is extracted by the weighted Hough transform.Finally,all of the tracks extracted in classification domain are accumulated to form a final SST track.Simulation results verify the effectiveness of the proposed algorithm.关键词
