| 摘 要： | 针对外辐射源单站无源目标跟踪精度问题,将一种基于Sterling内插公式的新的非线性滤波算法—中心差分卡尔曼滤波算法(central difference Kalman filter,CDKF)应用到系统中。仿真结果表明,与传统的扩展卡尔曼滤波算法(extended Kalman filter,EKF)相比,CDKF具有更高的定位精度,且不需要计算Jacobian矩阵,更易实现;而与无迹卡尔曼滤波算法(unscented Kalman filter,UKF)相比,CDKF只有一个待优化的比例参数,参数的选择更加方便,且定位精度更高,所需运算时间更少。

| Abstract: | For the problem of location performance of single observer passive object tracking based on opportunity transmitters,a new nonlinear filtering method CDKF based on Sterling interpolation formulation was applied to this tracking system.The simulation results show that CDKF is superior to the extended Kalman filter(EKF) in accuracy and is easier to implement without computing Jacobian matrices.Compared with unscented Kalman filter(UKF),CDKF method just has only one parameter to optimize,which makes parameter ... |
