试验任务中,一个飞行目标往往是多台测量设备同时跟踪测量,产生基于不同设备的同时刻同目标的多批真值数据,其拟合问题在航迹显示的数据处理过程中尤为重要。论文以6台测量设备的航迹数据为例,给出了数据拟合模型及计算机求解算法,并进行了仿真,结果表明拟合后的数据更接近目标真实,为今后研究多台套测量设备数据拟合,提高航显精度与时效奠定了基础。

In the test task, one flight target often involves multiple measurement devices tracking and measuring at the same time to generate multiple batch true value data of the same target at the same time based on different devices. The fitting problem is particularly important in the data processing of the track display. Taking the track data of six measuring devices as an example, the paper presents a data fitting model and a computer algorithm, and the simulation results show that the fitted data is closer to the target reality. In order to study more than one set of measuring equipment Data fitting, improve flight accuracy and aging laid the foundation.
