Gesture consistency of airplane target between static and dynamic measurements

对飞机目标静态与动态测量对比时的姿态一致性开展研究.介绍了目标特性测量中常用的几种坐标系,并给出了其相互转换关系.对静态测量和动态测量时典型的雷达视线和飞机目标的相对位置关系进行了分析,给出了静态测量和动态测量之间姿态解算的流程图.结合仿真实例,给出了某飞行航迹下雷达测量得到的飞机航迹结果,解算得到了飞行过程中极化坐标系和目标坐标系下雷达视线和飞机目标的相对位置关系.该研究成果有助于正确进行静态测量和动态测量时目标特性的对比,对于目标特性的动态仿真也具有一定的指导作用.

Gesture consistency of airplane target between static and dynamics measurements was studied. The most common coordinate systems in target characteristics measurement were introduced, and the transla- tion relationships were presented. The typical relative position relationship between line of radar sight and air- plane target was analyzed, and the flow chart of gesture translation between static and dynamic measurements was derived. A simulation example was given. The airplane flew with a typical path, the radar track of air- plane was simulated. The relative position relationship between line of radar sight and airplane target in polari- zation coordinate system and target coordinate system was derived while airplane is flying. The research can help to compare target characteristics between static and dynamic measurements rightly, and can also guide the dynamic simulation of target characteristics.
