A distributed target tracking algorithm for multiple stations
Abstract
A new distributed target tracking algorithm for multiple stations based on the basic principles of distributed estimation theory is proposed. Without loss of generality, consideration is given to the case where two substations and a main station (this main station may be the same as one of the two substations) coordinate to track a moving target, and the two substations use different coordinate systems. The two substations measure and estimate the states of the target, and send the subestimates to the main station according to some communication strategies. The main station combines the two estimates optimally and obtains better estimates. First the basic formula of the problem is used and the optimal equations for combining the subestimates of the substations using simple algebra is obtained. The simulation results show that the algorithm is effective; it gives the correct estimates quickly even if the subestimates of the substations are all wrong.
