| 摘 要： | 针对只测角机载无源定位跟踪具有收敛速度慢及定位误差大的缺点，在只测角定位跟踪模型中加入相位差变化率信息并在此基础上引入平方根不敏卡尔曼滤波（UKF）算法来实现定位与跟踪。仿真结果表明增加相位差信息能够改善定位性能，平方根UKF算法具有比EKF算更快的收敛速度和更高的收敛精度，实用性强。

| Abstract: | In order to solve problems of low convergence speed and large location error for airborne angle-only passive location and tracking,the phase difference changing rate is added to the angle-only location model.An square-root unscented Kalman filter(UKF) algorithm is introduced to realize location and tracking.Simulation results indicate that the location performance has been improved significantly with the information of phase difference changing rate added to the angle-only location model and the UKF algorit... |
