摘要

为了提高机载光电测量设备定位精度，搭建了机载光电测量设备目标自主定位系统。利用齐次坐标转换的方法，构建了机载测量系统跟踪目标时的目标定位方程和定位误差方程，并利用蒙特卡洛法分析目标自主定位误差。引入小波分析理论对定位误差进行优化以提高目标自主定位精度。对实验数据和飞行实测数据进行了分析，结果显示，采用小波分析理论优化目标自主定位误差可以大幅提高目标自主定位精度，提高幅度达到70%，得到的结果验证了目标自主定位技术的可行性和优越性。文中的分析方法和内容同样也适用于地面跟踪测量平台和舰载跟踪测量设备。

Abstract

To improve the accuracy of a photo-electric measuring device

an automatic positioning system for airborne photo-electric reconnaissance equipment was established. Firstly

the positioning equation and error equation of the target automatic positioning technology were constructed based on homogeneous coordinate conversion

and the Monte Carlo analysis method was used to analyze the error of the target automatic positioning technology. Then

the wavelet analysis theory was brought to optimize the positioning error to improve the position accuracy. By analyzing experimental data and flight test data

it shows that optimizing the target automatic positioning technology by wavelet analysis theory can substantially improve the target automatic positioning precision by 70%. These results verify the feasibility and superiority of the target automatic positioning technology. The analysis method is also applies to surface tracking and measuring platforms and the ship-based tracking and measuring equipment.
