摘要
为了解决雷达面临的四大威胁和无源定位系统定位精度偏低及被动工作的问题,多站有源无源联合定位系统正在成为研究热点。航迹起始是该系统对目标进行跟踪的首要问题。在航迹起始过程中,系统需要将有源观测点迹和无源观测点迹进行融合,其本质是异类源数据融合问题。分析了有源无源联合定位系统的航迹起始问题的特点,提出了一种针对有源无源联合定位系统的航迹起始方法。仿真实验结果表明了该算法的有效性。
To solve the problem of four threats in radar system and passive style and low precision in passive location system, the combination of active and passive location system in integrated active and passive style has become the focus of recent research. Track initiation is the chief problem of the target tracking in the system, in which active and passive measurement need to be fused, and the essence is heterogeneous sources data fusion. The characteristic of track initiation of the active and passive location system is analyzed, and a new track initiation algorithm is proposed. The simulation demonstrates the af- fectivity of the algorithm.
