基于STK的侦察卫星预警系统设计与仿真

侦察卫星可以全方位全天候的对全球进行侦察,对侦察卫星的预警是有必要的.文中首先基于Access数据库建立了侦察卫星数据库,主要针对光学成像卫星、雷达成像卫星以及电子侦察卫星三类;通过STK(卫星工具包)的STK/Connect模块实现了侦察卫星数据库与STK的连接,基于STK平台实时的显示了侦察卫星的在轨运行以及对地覆盖情况.文中通过VC来生成系统界面,首先通过界面来操作数据库信息,然后把卫星载入到STK平台,通过界面设定仿真时间,设定特定区域,仿真设定的时间段内卫星的运行及对区域的访问情形,通过STK的报告生成功能可生成卫星在此时间段内对区域的访问报告,根据报告可对访问该区域的侦察卫星进行预警.

Design and Simulation of Satellite Prediction

The reconnaissance satellite can all-weather and all-position reconnoitre the world.The prediction of the reconnaissance satellite is necessary.In the paper,a database of the reconnaissance satellites which mainly includes the optical imaging reconnaissance satellite,the radar imaging reconnaissance satellite and the electronic reconnaissance satellite is founded.The paper shows satellite's circulating and real-time coverage to the ground by connecting the database to the STK(Satellite Tool Kit)with the module of STK/Connect.The interface of the system is created by VC.First,operating the database from the interface.Secondly,loading the reconnaissance satellite from the database.After that,setting the simulation time and the specific area from the interface and a visiting report in the simulation time can be gotten by the function of creating report in STK.A prediction of the reconnaissance satellite can be made through the report.
