| 摘 要： | 坐标转化在雷达信号处理中应用得非常广泛,随着对实时性要求的不断提高,传统的方法已经不能满足要求。在介绍CORDIC(Coordinate Rotation Digital Computer)算法的基础上提出了一种基于该算法的能够同时进行两路数据的坐标转换的FPGA实现方案。该方法以全流水线结构实现,转换速率快,精度高,能够满足现代雷达信号处理中对实时性的要求,并在实际系统中得到了应用。

| Abstract: | The coordinate conversion is popular in modern radar signal processing,but the traditional technique of transformation is not satisfied because of high realtime requirement.This paper firstly makes an overview of CORDIC,and then introduces a FPGA solution that can handle the coordination conversion of two channel data simultaneity.This solution is implemented in full pipelined architecture,and has the advantage of high precision and speed which can satisfy the realtime requirement of modern radar signal processing. |
