| 摘 要： | 本文导出了在惯性坐标系内利用线性测量卡尔曼滤波器(LMKF)来估值海上机动目标的状态估值器。LMKF 可以用于非线性测量条件下的目标状态估值。同时,LMKF 的公式比延伸的卡尔曼滤波器(EKF)要容易推导得多。在飞机坐标系里用蒙特卡罗方法进行了大量的数学模拟。模拟结果表明,两种滤波器的估值误差相同,但是LMKF 只需要比较少的计算量。应用线性测量的方法,导出了在飞机地理水平面坐标系内的LMKF。该滤波器有较高的溶液精度和较少的计算量。

| Abstract: | A state estimator is derived in inertial coordinates for estimating a ma-neuvering target on the sea by using a linearizatlon measurement Kalman filter(LMKF).The LMKF can be used to estimate a target under nonlinear measurements andthe formulas of the LMKF are more easily derived than those of the extended Kal-man filter(EKF) Monte-Carlo simulations of the LMKF and EKF are carried outin airplane coordinates.These simulations show that the estimation errors are the samefor both filters.but that the LMKF requires less computation applying method oflinearization measurement,the LMKF in airplane geographic small plane coordinatesis described.This filter has the advantages of higher accuracy and less computation-al burden |
