| 摘 要： | 基于定向概率数据关联滤波(DPDAF)算法,根据红外传感器对目标方位角与俯仰角分辨率不同的特性修正了似然函数,并利用等效观测噪声协方差阵修正滤波增益的思想,构造了一种旨在提高红外传感器跟踪性能的修正定向概率数据关联滤波算法.蒙特卡洛仿真结果表明,新算法对红外目标的跟踪具有比DPDAF更好的跟踪性能.

| Abstract: | First based on Direction Probabilistic Data Association Filter(DPDAF) and the characters of infrared sensor,this paper modify the likelihood function.Then,it presents a new algorithm(MDPDAF)based on the way through which gain matrix is modified by covariance matrix of equivalent measurement noise.The results of simulation show it working as expected well. |
