Design of Synthetic Aperture Radar Object Simulator Based on PCI

介绍了一种基于 PCI 接口的合成孔径雷达目标模拟器的设计与实现。该模拟器将已存于 PC 硬盘中的雷达原始回波数据或按照某种算法生成的雷达仿真数据,转换成 I/Q 两路视频信号。着重介绍了系统的硬件结构设计和软件实现功能,给出了选用的主要的芯片型号。本设计已应用于某合成孔径雷达信号模拟器系统中,使用证明该系统工作稳定,实现了设计中要求的功能。

A design of synthetic aperture radar object simulator based on PCI is described. The simulator translates the radar’s original echo data or radar’s emulative data generated by some arithmetic into I/Q two lines video frequency signals. The design of the system’s hardware and software is emphasized, and the primary chip model is presented. The design has been applied in certain synthetic aperture radar object simulator system, it is proved that the system is running steadily, and the demanded function has been realized.
