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 results show that the recursive upper and lower bounds are close to the average CRLB of tracking systems as the sample-collecting time increases.
