摘要
针对高分辨率遥感卫星数据机动接收处理的特点,提出一种具有一体化、通用化和小型化特点的高速遥感数据接收处理平台。该平台通过采用嵌入式变频与光电前端技术、嵌入式高速解调技术和ATCA高性能计算架构等技术实现了2 Gbps以上的高分辨率遥感数据小型化接收处理,可应用于高机动遥感卫星地面接收处理系统中。
The development of current sensing satellites are characterized by high accuracy,large amount of data,high data rate,a variety of formats,and the transmitted data are mostly compressed,encrypted,scrambling and error correction encoded. Higher requirements have been proposed to ground station especially for small motorized station. In this paper,a kind of universal small high-resolution remote sensing satellite data reception and processing platform was proposed. Through the use of embedded frequency conversion,optoelectronic front-end technology,embedded high-speed modem technology and ATCA highperformance computing architecture technology,the platform can achieve over 2 Gbps high-resolution remote sensing data receiving and processing. The systems can be applied to high mobility of remote sensing satellite ground receiving and processing systems.
