Three dimensional time-delay maneuvering target tracking in slow velocity

The kinematical state model of the target is a key problem in the maneuvering target tracking. Based on the acceleration equation, we proposed for the target a kinematical time-delay state model in low velocity. An H-infinity recursive filter is applied to track the target. In the application of the 50m-model of a large radio telescope , the experimental results show that the algorithm remarkably improves the tracking performance of the Leica obviously when the speed of the cabin is constant.
