摘要
针对合成孔径雷达(SAR)的微型化发展需求,提出了一种基于Z7的微型SAR实时成像系统。该系统采用高度集成化及模块化设计,将传统的SAR综合处理单元集成在一块微型板卡上实现全部功能,包括信号产生、中频采样、信号处理、数据处理及数据记录功能。在满足总体成像技术指标的前提下,减少了系统设备体积、重量及功耗,实现了微型SAR实时成像技术。该系统经过多个架次的微型无人机试飞验证,取得了令人满意的成像效果。
For the miniaturization development needing of the synthetic aperture radar （SAR ）, a miniature SAR on-board imaging processing system based on z7 chip is proposed. The functions including signal generating, intermediate frequency sampling, signal processing, data processing and data storage are implemented on a miniature board as same as the traditional SAR Comprehensive processing unit, in which highly integration and modulation design are employed. Under the premise of satisfying the comprehen- sive imaging technical indicators, the miniature SAR on-board imaging technology is implemented with the reduction of equipment size, weight and power. The effectiveness of the system is verified through several flights test on a miniature UAV, and the imaging results are satisfied.
