摘要
针对传统算法难以实现对慢小目标进行有效航迹起始的问题,提出了一种图像处理Hough变换的慢小目标航迹起始方法。引入了最小外接矩形的长宽比(F3)、占空比(F2)和像素值(F1)3个参量值作为Hough变换的加权因子,并运用图像标记技术提取积累区域上述加权因子,最后通过加权Hough变换成功起始慢小目标航迹,提高了雷达对慢小目标的探测性能。仿真结果验证了该算法的有效性。
Aiming at the problem that the traditional algorithm cannot initiate the slow and small target（ SST） track effectively,a track initiation method for SST based on image processing Hough transform is proposed. The parameters of the minimum circumscribed rectangle,consisting of F3,F2 and F1,are introduced as the weighting factors of Hough transform,and these parameters are extracted in accumulation region by image marking technique. SST is successfully obtained by controlling the weighting factor of Hough transform,which improves the detection performance of the radar to the SST. Simulation results verify the effectiveness of the proposed algorithm.
