对运动辐射源的单站无源伪线性定位跟踪算法

本文针对只测向单站无源定位中推广卡尔曼滤波（EKF）算法具有不稳定性等缺点，在只测向（BO）定位算法的基础上增加方位角速率观测信息，提出了一种对运动辐射源的单站伪线性卡尔曼滤波定位方法并进行了计算机仿真，它相对于只测向方法提高了定位误差的收敛速度。它可用于无源侦察监视或导弹制导等要求快速收敛的场合。

A passive moving emitter location and tracking algorithm by pseudo-linear method

According to the erratic filter behavior of traditional extended Kalman filter (EKF) of bearing only algorithm in passive emitter location,in this paper,we introduced a new pseudolinear tracking model and tracking algorithm of moving emitter,which added angle velocity measurement information on the basis of bearing measurement.It has shorter converging time and more stable merits compared with bearing only method from computer simulation.It is useful in the cases such as missile guidance or passive surveillance which demands fast convergence rate.
