飞行目标航迹显示中的数据拟合方法

Data-fitting Method in the Flight Path Display

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 some equipment test, multi-group data are obtained by many sets of measuring equipment that track a same flying target at the same time. It is valuable how to fit these data to form a new one for computer better displaying the flight path. This paper puts forward a data fitting model and a computer calculating method, through an example of six groups of data fitting. The simulation results show that the fitting effect is more close to the real value. As a future refer-ence, this paper provides a way for accurately and efficiently solving more data fitting problem.
