一种无格点动态规划检测前跟踪算法研究
|
摘要
目标的多样化和环境的复杂化,对现代雷达的探测能力与航迹处理提出了更高的要求。随着雷达技术的迅速发展,弱目标的检测与跟踪也受到了更为广泛的关注。检测前跟踪技术可以减少虚假航迹,提高微弱目标的检测和跟踪性能。为改善传统的基于动态规划的检测前跟踪算法计算复杂的缺点,提出了一种无格点DP-TBD改进算法,分析了适用模型,给出了运动及量测模型。仿真实验表明,该算法具有较好的检测跟踪性能。
The diversity of targets and the complexity of the environment put forward higher requirements for the detection ability and track processing of modern radar. With the rapid development of radar technology, the detection and tracking of weak targets has also received extensive attention. Track-before-detect(TBD) technology can reduce false tracks and improve the detection and tracking performance of weak targets. In order to improve the limitation of the traditional pre-detection tracking algorithm based on dynamic programming, an improved lattice-free DP-TBD algorithm is deduced. The applicable model is analyzed and the measurement model is given in this paper. The simulation results prove that the algorithm has good detection and tracking performance.
