| Abstract: | The application of Kalman filtering algorithm in passive tracking system is studied.First,the filter is designed by separating the filtering and controlling,and the extended-Kalman-filtering formula is deduced;then the performance of the Kalman filtering algorithm is simulated with the data obtained from the passive tracker.The results show that the algorithm is effective,its average runtime is approximately 1.5 ms,and can be applied to the realtime signal processing in passive tracker. |
