| 摘 要： | 介绍了高分辨率逆合成孔径雷达中频回波信号形式。根据高分辨雷达回波信号特点，采用TMS320C6713和AD9857，设计了一种具有实时模拟能力的雷达中频回波信号源。针对DSP实时生成目标特征数据的速度问题，文中重点作了探讨，提出了一种基于直接数字合成思想的算法，给出了信号模拟的流程。实践证明，该模拟器达到了设计要求。

| Abstract: | First, the IF signal format of a high resolution ISAR radar is introduced. And based on it, using TMS320C6713 and AD9857, a real - time radar IF signal simulator is designed. Aiming at the problem of data-generating rate by DSP, some discussion is made, and a DDS based arithmetic is put forward. The flow chart of signal simulation is presented. Practice shows the requirement of design is met. |
