在本文中，研究了具有移动测距传感器的跟踪系统的目标跟踪问题。与大多数以前的研究不同，测量中的加性和乘性噪声都被考虑在内。提出了一种最佳协调策略，包括传感器选择和传感器运动，以最大限度地提高跟踪精度。特别是，通过充分利用目标函数的性质，可以显着减少原始优化问题的搜索空间和变量。基于这种减少，设计了三种算法，分别用于以下目的：1）任务传感器的有效选择； 2）减少任务传感器的组合； 3）有效搜索最佳传感器运动。通过模拟说明了所提出的协调策略的性能。
In this paper, the target tracking problem is investigated for a tracking system with mobile range-only sensors. Being different from most previous studies, both additive and multiplicative noises in measurements are taken into consideration. An optimal coordination strategy, including sensor selection and sensor motion, is proposed to maximize the tracking accuracy. In particular, by fully utilizing the properties of objective function, the search space and variables of the original optimization problem can be significantly reduced. Based on this reduction, three algorithms are designed, respectively, for the following: 1) efficient selection of task sensors; 2) reduction on combinations of task sensors; and 3) efficient search of optimal sensor motion. The performance of the proposed coordination strategy is illustrated by simulations.
