摘　　要：粒子滤波理论适用于在非线性和非高斯环境下的目标跟踪与检测。文中基于序列重要性采样定理,提出了模型环境和多雷达目标检测的递归贝叶斯TBD算法。此算法在基本粒子滤波算法SIR的基础上,采用多模型粒子滤波器实现了多雷达目标的检测。仿真结果表明,算法能够有效地进行目标跟踪与检测。Particle filter is a robust algorithm for target tracking and detection in non-linear and non- Gauss circumstances. Based on the theories of sequential importance resampling（SIR）, this paper sets up a model and proposes a recursive Bayesian algorithm for multiple target TBD application. The algorithm is realized by using multiple model particle filter. Simulated results show that the method can work efficiently in tracking and detection.
