雷达不同工作模式下跟踪任务的信息需求分析

摘要

雷达采用不同工作模式跟踪目标是有差异的.给出了跟踪任务信息需求的分析方法,并在计算由传感器量测带来信息增量的基础上,重点对边跟踪边扫描和跟踪加扫描两种模式对跟踪效果的影响进行了研究.实验结果分析了这两种工作模式下雷达量测间隔与跟踪任务信息需求之间的关系.从结论可分析出,与间隙量测方式相比,持续量测可以带来较为理想的跟踪效果,且信息需求能在较短的时间内予以满足.%The different work mode of active radar could affect the tracking effect. Firstly, tracking mission information requirement analysis method is given. Then the information gain brought by sensor measurement is computed. The tracking effects in Tracking while Scaning (TWS) and Tracking and Scaning (TAS) mode are researched separately. Finally, the relationship between tracking information requirement and radar measurement mode is discussed according to some experiment results. The results show that be compared with interval measure, the continuance measure can bring ideal effect, and the information requirement can be satisfied in a short time.
