高速率遥感卫星接收与处理系统的设计与实现

为成功接收搭载分米级分辨率的SAR（Synthetic Aperture Radar，合成孔径雷达）载荷低轨遥感卫星数据，验证卫星载荷工作状态和性能，本项目研发一套Ka/S双频段遥感卫星接收与处理机动站。针对窄波束高动态卫星跟踪、多通道高速率遥感数据星地传输的重难点，本文着重从窄波束高动态目标卫星跟踪、超高速高性能全数字解调以及高精度双模式自适应盲均衡等关键技术进行研究。通过试验验证技术路径正确、措施有效，可为后续相关系统研制提供技术参考。

Design and implementation of high-rate remote sensing satellite receiving and processing system

In order to successfully receive the low orbit remote sensing satellite data carrying the SAR payload with decimeter resolution, and verify the working state and performance of the satellite payload, this project developed a set of Ka/S dual band remote sensing satellite receiving and processing mobile station. Aiming at the key and difficulties of narrow beam high dynamic satellite tracking, multi-channel high-speed remote sensing data of satellite-to-ground transmission, this paper focuses on key technologies such as narrow beam high dynamic target satellite tracking, ultra fast and high-performance all digital demodulation, and high-precision dual mode adaptive blind equalization. It is verified that the technical path is correct and the measures are effective through experiments, which can provide technical reference for the subsequent development of related systems.
