摘要
测向/时差联合定位算法具有仅需要2个节点即可实现良好的定位精度,具有很好的应用前景。在双站测向/时差联合定位的原理基础上,提出一种基于测向/时差的最小偏度单形采样不敏卡尔曼滤波(UKF)定位算法。通过计算机仿真实验表明,基于最小偏度单形采样的UKF的测向/时差联合定位算法收敛速度快,定位精度高。
The two-station DOA/TDOA joint location algorithm has wide application prospect,as its high location accuracy.At First,two-station DOA/TDOA location principle is introduced,the minimal skew simplex sampling unscented Kalman Filter(UKF)algorithm based on DOA/TDOA parameter measurement is derived.The performance of rapid convergence velocity and the high location precision is validated with the simulation.
