跟踪雷达伺服系统中坐标转换问题的研究

摘要

舰载综合体配置雷达跟踪伺服系统中，一旦中心信息处理系统发出了目标指示命令，综合体开始动作，之后的每一个工作状态都存在复合控制问题。例如，在调舷状态，直观看来，雷达天线要与载体同步调转动作；在作战状态，雷达天线要与载体一起稳定瞄准目标。在进行复合体控制时，必须对不同坐标系下产生的信息进行实时的坐标转换，使之在同一坐标系下进行数据处理，否则得出的结果是不正确的或者误差很大，使雷达不能满足跟踪精度的要求。本文将对舰载综合体配置雷达跟踪伺服系统中，需要进行的坐标转换进行详细的说明。%In the servo system of tracking radar of a Shipboard syntheses, once the center information system sending orders, the blended control exists in every operation. For example, when the swinging motion orders were sent out, the antenna of radar should act accord with the artillery. In the battling state, the antenna and the artillery should be aiming at the same object steadily. We should transform the data that engendered in different coordinates into one coordinate so as to deal with them. Otherwise, the calculation results may be wrong or have a very large error. This paper conducted a comparatively particular research on the coordinate transformation.
