摘要
为了在重杂波区内检测出运动的目标,提出了一种修正的Hough变换算法用于初始航迹的建立。与传统的算法相比,修正算法充分利用目标的运动学信息,选取了更为合适的变换参量,仅利用较少拍数的量测就可以完成起始,能够在检测概率较高的环境下具有良好的起始性能。计算机仿真结果表明,算法能够克服传统算法的多拍扫描,大大缩短实际的计算量和起始时间,实现对航迹起始的在线改进。
A track initiation technique is proposed to detect targets in heavy clutter using a modified Hough transform method to initiate the tracking.Contrast to traditional algorithm,the modified one involves kinematic information.It selects the more appropriate transform parameters to finish the track initiation with less beats.It has better initiation performance.we perform the computer simulations of the better tracking algorithm.The analysis of simulation results,indicates preliminarily that our better algorithm does restrain multi-beats scan and reduce the computational complexity tracking initiation time.
