| 摘 要： | 针对DS理论的目标识别无法满足组网雷达对同步性和实时性要求的问题,利用模糊隶属函数求解似然函数确定DS理论所需的基本概率赋值,建立基于矩阵分析的DS理论数学模型,并讨论该算法在组网雷达中的应用,根据实例进行仿真。结果显示:在不损失融合精度的前提下,收敛速度有效提高,计算所需时间并不随传感器数目的提高而出现指数爆炸。

| Abstract: | Considering the problem that the target recognition based on DS evidence theory can't satisfy the synchronous and real-time requirement of netted radar,we used fuzzy membership function to work out likelihood function,built up a mathematic model of DS evidence theory based on matrix analysis,and then discussed the application of it in netted radar. Simulation was made for a practical example. The results showed that this algorithm can improve its convergence velocity without losing any precision,and the inc... |
