摘要
针对基线较短情况下传统的双站三角测距精度不高的问题,利用双站方位历史信息建立了双站无源定位模型,该模型可以利用多种线性估计器来求解。采用最小二乘算法来实现对目标距离的估计。通过仿真实验说明该模型能够实现对目标距离的估计,证明该算法用于无源定位是有效的。
The triangulation ranging algorithm is inaccuracy when the baseline is short. The passive location model is pro- posed using the dual-observer historical azimuths. The solutions of the model can be solved by some linear estimators. The target distance is estimated by the least squares estimator. The simulation results prove that the model and the method are feasible.
