电子地图在边扫描边跟踪侦察系统中的应用研究

Application of electronic map in track-while-scan surveillance-system

提出一种利用电子地图信息改善边扫描边跟踪侦察系统性能的新算法。利用地面目标一般沿着道路或河流运动的特性 ,从电子地图得到目标周围道路或河流信息 ,通过假设检验将其与跟踪滤波器输出进行综合 ,修正跟踪滤波器的估计结果。该方法在仿真和实际侦察系统中取得了较好的结果。

Anewapproachtoimproving the performance of track-while-scan (TWS) surveillance-system using electronic map is presented. Ground targets are always constrained by roads or rivers. The electronic map provides information of roads or rivers around the target, which is used to modify the estimation of tracking filter by hypothesis testing. Simulation results of real scenarios show good performance of the algorithm.
