基于区分度增量和CPCRLB的传感器管理算法
摘要
针对传感器管理中存在的能量和资源有限问题
提出了一种基于区分度增量和条件后验克拉美—罗界(CPCRLB)的传感器管理算法
首先推导了CPCRLB在无源传感器粒子滤波情况下计算公式
然后采用条件后验CPCRLB作为矩阵遗传的适应值对传感器分配方案进行选择
同时计算每个目标的区分度增量
合理分配传感器资源。仿真结果表明:该算法能较好地实现传感器的分配
并降低了整个跟踪过程中的能耗。
Abstract
To solve the energy limitation problem in sensor management
an algorithm based on discrimination gain and CPCRLB is proposed. Deduce calculation formulas to calculate CPCRLB for negative sensor with particle filtering
adapts CPCRLB as the fitness of matrix genetic algorithm. The discrimination gain of each target is calculated to allocate the sensor resources properly. Simulation result shows that the proposed algorithm can achieve a good performance in sensor assignment and reduces energy consumption in target tracking.
