航迹起始算法及性能仿真

Algorithm of Track Initiation and Performance Evaluation

在深入研究基于逻辑的航迹起始方法和基于Hough变换技术的航迹起始方法的基础上,把基于逻辑的方法和Hough变换法相结合,提出了基于目标运动状态的航迹起始算法。该算法首先利用目标的位置信息形成候选目标航迹,在候选目标航迹扩展过程中,利用来自同一个目标的量测数据在较短时间内(相邻2个采样周期)具有相同的运动状态,利用目标的运动状态对候选航迹进行检验。进行了性能比较仿真,仿真结果表明:该算法在正确航迹起始概率上和基于逻辑的方法相当,但其虚假航迹起始概率远低于其他航迹起始方法;并且对存储要求低,适于工程应用。

Based on the studying of Logic-Based approach and Batch-Based method for track initiation, a novel track initiation algorithm based on target dynamic state was developed. Considering the target dynamic states are constant in the interval sampling periods, the target dynamic states were used to test the candidate tracks in the algorithm. The statistical performance analysis of track techniques in terms of their track detection probabilities and false track probabilities was dealt with. The simulation results indicate that the presented approach has lower false track probabilities than other methods, and the memory requirement is lowered efficiently.
