摘要
单机无源定位跟踪技术具有隐蔽性强、设备简单以及系统相对独立等优点,有着广阔的应用前景。为了提高定位精度和收敛速度,在现有的基于EKF单机无源定位算法的基础上,推导了基于MGEKF的定位算法,以解决EKF算法的不稳定性和对滤波初始值要求高的问题。与EKF定位算法相比,MGEKF定位算法对滤波初始值的要求相对较低,MGEKF定位算法提高了定位精度、收敛速度和稳定度,定位结果能够满足实际需求。
The stand-alone passive location and tracking technology has such characteristics as high concealment capability,simple equipment and relative independence,and it has wide application prospects. In order to improve positioning accuracy and convergence speed,the MGEKF-based location algorithm is deduced based on current EKF-based single-station passive location algorithm and solves the problems of instability and requirement for high filtering initial value of EKF-based algorithm. Compared with the EKF-based location algorithm, MGEKF-based location algorithm requires lower filtering initial value. The MGEKF-based location algorithm can improve the positioning accuracy,convergence speed and stability,and the positioning results can meet the actual demand.
