基于卡尔曼滤波算法的三站无源时差定位精度分析

Accuracy Analysis on Tri-Station Passive TDOA System Based on Kalman Filter Algorithm

摘要无源时差定位作为无源定位中一个重要技术手段，在反隐身、反预警和抗反辐射导弹方面的作用日益突出。文章在研究卡尔曼滤波算法的基础上，给出了基于卡尔曼滤波算法的三站无源时差定位精度计算方法，并给出了数值计算结果。

As an important technical method in the passive location, the passive TDOA technique has exerted an increasingly significant effect on anti-stealth, against early warning and against ARM. Based on the study on the Kalman Filter Algorithm, the accuracy calculation method of the tri - station passive TDOA is presented in this paper, which is based on the Kalman Filter Algorithm. And the numeric calculation results are also presented.
