雷达信息处理系统中的坐标变换问题研究

Research on Coordinate Transformation Under Radar Information Processing Systems

在雷达信息处理过程中,首先需要进行目标观测数据的空间同步,即将数据变换到一个公共坐标系中,然后才能进行各种数据处理。本文主要讨论不同坐标系之间的坐标变换及转换误差,并提出了在雷达信息处理系统中使用地心坐标系作为统一坐标系的一种新的坐标变换方法以减小地球曲面误差的影响。

In the process of radar information processing, the observed target data should be firstly synchronized spatially, that is, the data should be transformed into a common coordinate system, then, all sorts of data can be processed. This paper focuses on the coordinate transformation and the transformation errors from one coordinate system to another, and brings about the new conversion method of using ECEF coordinate as the unified coordinate in order to lower the effects of the earth curvature errors.
