捷联惯性技术在相控阵雷达中的应用

Application of Strap-down Inertial Technology in Phased-array Radar

简述了捷联惯导的基本原理,构建了雷达使用捷联惯导的数学模型,分析了雷达工况对惯导系统的要求,并通过试验证明捷联惯导系统满足雷达多种工作方式应用。另外,文中对实际工程应用存在的高精度标定问题也给出了基于双经纬仪交汇法的惯性坐标系下雷达电轴标定方案,并进行了实验验证。

The ultimate principle of strap-down inertial navigation system （SINS） is described. The mathematical model of applica- tion is structured. The requirement for SINS from radar operating mode is analysed, and it is proved that SINS can meet the re- quirements of various radar operation application by experiment. In addition, the scheme of radar electric axis calibration in inertial coordinate system based on bi-theodolite intersection method is elaborated, meanwhile the scheme has been verified by test.
