摘要

靶场弹道坐标测量的精度和稳定性是检测武器系统性能的重要技术指标。为获取高精度的弹道三维坐标，提出了使用Helmert方差分量估计、最小二乘多站交会-Helmert方差分量估计两种方法来处理雷达和光电经纬仪的观测数据。首先，介绍了雷达、光电经纬仪交会测量原理和数学模型，以及Helmert方差分量估计模型及计算过程。然后，研究了将验后估计思想加入到交会模型的实现方法。最后通过对算例数据进行解算分析，证明本文方法的有效性和可行性。结果表明：最小二乘多站交会与Helmert方差分量估计结合法，在

Abstract

The accuracy of the measured ballistic coordinates in the shooting range are key technical factors which determine the performances of the weapon system. In this paper

we used Helmert methodology in terms of Helmert type for estimating variance component (HTEVC) and integrated multi-station intersection least squares (MSI-LS) and HTEVC to process the joint radar and photoelectric-theodolite measurements. The mathematical model and measuring geometry were introduced. The estimation processes and models of HTEVC were illustrated. The method that integrated posteriori estimation into the MSI model was investigated. Finally

the effectiveness and feasibility of our method were certified by example data. The simulation results indicate the integrated MSI-LS and HTEVC can achieve less than 1 m accuracy in

and

directions.
