基于最小二乘的导弹外弹道精度分析系统

The Analysis System of Missile's Trajectory Accuracy Based on Least Squares Estimate

外弹道测量系统中,合理的布站能提高整个系统对目标的跟踪测量能力,优化的交会方案可提高弹道求解的精度。采用最小二乘法,运用协方差矩阵分析轨道参数精度,通过仿真计算,着重研究如何获取最优交会方案,以及不同的交会方案对外弹道求解精度的影响。试验结果表明,该算法可为外测数据事后处理提供高精度、快速的光测数据处理报告,为合理调整站点布局和人力资源提供依据。

At the system of trajectory measure, logical station disposal can improve the tracking ability of the measurement and controlling system, the intersectional scheme.of multiple tracking telemetry and command （TT＆C） station is important for improving accuracy of the result trajectory. This dissertation devise computer emulator using the method of the least squares estimation, discuss how to acquire the optional intersectional scheme of multiple TT＆C stations and how is the intersectional scheme related to precision of resultant trajectory.
