机载火控雷达中的坐标变换

机载火控雷达在目标探测、地面成像时要求天线波束具有某种稳定方式,如偏航稳定、水平面上稳定、偏流稳定。另外飞机航电系统在不同的工作方式时,需要雷达提供不同坐标系下的数据,这些都涉及到坐标变换的问题。本文详细介绍了机载火控雷达中所涉及的坐标系及相关概念,描述了各个坐标系之间的变换算法,最后介绍了在机载火控雷达中的具体应用。

Coordinate Transformation for Airborne Fire Control Radar

Antenna beam is required to some ways of space stabilization when airborne fire control radar detects targets or imaging,such as heading stabilization,horizon stabilization,velocity vector stabilization.In addition,radar is required to provide data in different coordinate systems to meet requirements of aircraft aviation electronic system operating in different mode.Coordi- nate system transformation is involved in that.This paper introduces coordinate systems and related concepts for airborne fire con- trol radar and describes coordinate transformation algorithm between these coordinate systems.Finally,some applications to air- borne fire control radar are suggested.
