| 摘 要： | 针对高重频雷达距离模糊可能会导致目标航迹不连续即发生跳变的问题,提出了一种改进的动态规划检测前跟踪算法,该方法在传统动态规划的基础上加入了后续状态估计并改进了动态规划搜索策略.它利用目标初始状态信息对目标后续状态进行估计并进行航迹跳变判决,再根据判决结果选择动态规划搜索策略,进而得到最优的目标试验航迹.文中利用改进的动态规划算法分别对距离模糊后跳变与未跳变两种情况的弱目标进行检测.仿真结果验证了该算法可以提高雷达回波中弱目标的检测性能,算法实际可行有效.

| Abstract: | In this paper,an improved dynamic programming based track-before-detect algorithm is proposed to detect weak target,whose track may be discontinuous due to the range ambiguity for high pulse repetition frequency(HPRF) radar applications.In the new algorithm,the latter successive states are estimated and the search strategy is improved.Firstly,the latter successive states are estimated and then the continuity of track is judged.Secondly,a best tentative track path selection is made recursively for each scan ... |
