Ding Wang · Electronic Information Warfare Technology · 2008
The location and tracking problems for stationary target and moving target with constant velocity are discussed based on the T-R type of bistatic radar system.Firstly a kind of analytical geometry location method is researched for stationary target and the analysis of its location accuracy is given;and then a pseudo-linear kalman filter(PLKF) algorithm and an analytical geometry location-kalman filter(KF) algorithm based on angle and distance sum measurements are presented for moving target with constant velocity,the computer simulations show that both of the two algorithms are better than the extended kalman filter(EKF) algorithm in the aspect of location accuracy,and both of the two algorithms have great practicability.
