STK软件在数字目标场景仿真中的应用

Application of STK Software in Digital Target Scene Simulation

为了解决数字目标场景仿真中缺少逼真的战场态势和目标轨迹显示的问题,提出了利用卫星工具包(STK)软件进行三维战场环境显示的思路和方法。通过研究STK二次开发接口和对象模型库,在基于微软基础类(MFC)的窗口应用程序中利用STK的组件对象模型(COM)接口进行二次开发,实现了在窗口应用程序中直接嵌入STK三维显示窗口,并利用STK的星历文件实现了轨迹信息的导入和显示。同时,给出了雷达坐标系下目标位置与经纬度的转换方法。该研究解决了数字目标场景仿真中三维场景显示的问题,为雷达提供了更加真实的仿真场景,提高了用户体验度,具备较高的工程应用价值。

In order to solve the problem of lack of realistic battlefield situation and target trajectory display in digital target scene simulation,the idea and method of using satellite tool kit(STK)to display three-dimensional scene environment is presented.By researching the STK development interface and object model library,the method of development using STK component object model (COM)interface in Windows application based on microsoft foundation class(MFC)is discussed,the embedding of STK three-dimensional display window directly in Windows application is realized,and the trajectory information is imported and displayed using STK ephemeris file.At the same time,the conversion method of target position between radar coordinate and latitude and lon- gitude is given.In this research,the problem of the three-dimensional scene display in the digital target scene simulation is solved, the more realistic simulation scene for the radar system is provided,and the user experience is enhanced,so the research has high engineering application value.
