| 摘 要： | 为了评估跟踪系统在不完全量测下的跟踪性能,该文利用投影定理给出了修正的去偏转换量测卡尔曼滤波(UCMKF)算法,进一步利用修正的黎卡提方程与修正的克拉美-罗下界(CRLB)给出了跟踪系统统计意义下估计误差协方差一致有界的充分条件,以及跟踪系统统计意义下CRLB的一组递推上下界。最后,Monte-Carlo仿真表明:随着采样时间的增加,递推上下界逐渐逼近了跟踪系统统计意义下CRLB的枚举真值。

| Abstract: | In order to evaluate the tracking performance of tracking systems with intermittent observations,a modified unbiased converted measurement Kalman Filtering(UCMKF) algorithm is presented by means of projection theorem.A sufficient condition for uniform boundedness of the average of estimation error covariance,and a group of recursive upper and lower bounds of the average Cramer-Rao low bounds(CRLB) of tracking systems are obtained using a modified Riccati equation and a modified CRLB.Monte-Carlo simulation r... |
