机载SAR超高速数据采集技术研究与系统实现

Research on an Ultra High Speed Data Acquisition System in Airborne SAR and its Implementation

以机载SAR应用为背景 ,研制超高速数据采集模块 ,通过采集系统两种结构方式的设计与实验 ,对系统实现过程中的关键技术进行了分析与研究。对比两种结构方式 ,选用多路并行存储技术进行系统设计 ,并应用于实际系统中 ,得到了较好的实验结果。

An ultra high speed data acquisition systems used in airborne SAR is introduced in this paper. By designing and experimenting with data acquisition systems of two kinds of structure, several key techniques for implementation high speed system are discussed. Through comparing two structure, the multichannel-parallel storage structure is selected. The practical application achieved good effects.
