一种机载电子对抗设备测向精度验证方法
|
摘要
机载电子对抗设备外场挂飞阶段验证测向精度时缺少精确的基础数据。介绍了几种常用的坐标系及坐标系间的变换方法,并利用直角坐标系的正交变换技术建立一种计算相对角度的模型,用于提供精确的基础数据,以验证机载电子对抗设备测向精度。最后进行了典型场景下的仿真验证。
The airborne ECM equipment lacks accurate basic data when verifying the direction-finding accuracy during the field flight phase. This paper introduces several commonly used coordinate systems and transformation methods between coordinate systems,and uses the orthogonal transform technology of Cartesian coordinate system to build a model for calculating relative angles,which is used to provide accurate basic data to verify the direction-finding accuracy of the airborne ECM equipment. Finally,the simulation verification is carried out under typical scenarios.
