摘要
首先介绍了二维测向系统中姿态补偿的必要性和实现方法,并对各文献内容进行了阐述和比较,引入了坐标变换的方法进行姿态补偿。接着讨论了不同坐标系及之间的变换关系,给出了变换公式,最后介绍了舰载平台二维测向系统的坐标变换方法和步骤,并对实时姿态补偿的解算方法进行了基于现场可编程门阵列(FPGA)的实现。
This paper firstly introduces the necessity and relization method of attitude compensation in 2-D direction finding(DF)system,elaborates and compares the content of various literatures,introduces the method of coordinates transformation for attitude compensation,then discusses different coordinate systems and their mutual transfornation relations,and gives the transform formulas,finally introduces the coordinate transformation method and steps of shipborne platform 2-D DF system,performs the realization based on field programmable gate array(FPGA)to the calulation method of real-time attitude compensation.
