提出了一种基于两观测站的三角交叉法对机动目标无源定位的算法 ,不是采用传统的对机动目标位置进行估计 ,而是直接对机动目标的位置偏差进行估计滤波 ,使定位的模糊区域迅速缩小 ,以达到快速定位跟踪的目的。列出了对位置偏差估计的状态方程和测量方程 ,用加权的最小二乘估计和卡尔曼滤波算法 ,实现了定位和跟踪。进行了计算机仿真 ,得到了良好的效果。 A new algorithm based on triangulation of two observatories is proposed. Passive maneuvering target positioning algorithm is not used to estimate the position of maneuvering target. Instead, the position error of maneuvering target is estimated and filtered, Quickly narrowed to achieve the purpose of rapid positioning and tracking. The equation of state and the measurement equation for estimating the position deviation are listed. The weighted least-squares estimation and Kalman filter algorithm are used to locate and track the position error. Have carried on the computer simulation, obtained the good effect.
