Abstract
With conventional Kalman filtering,it is required that the data of phase difference change linearly or nearly linearly. But in practice, this condition can not be fulfilled. To improve the localization algorithm precision for single site passive location, this pa- per presents an idea of differential-Kalman filtering, which includes the advantages of differential filtering and Kalman filtering and solves the problems of high constriction condition of Kalman filtering and low precision of differential methods. The simulation results show that the differential-Kalman filtering has much higher filtering accuracy than differential filtering,and has wider application than Kalman filtering.关键词
