摘要
海洋二号卫星微波散射计是国内首部星载微波散射计,在轨信号处理设计与实现方法是海洋二号卫星微波散射计在轨优异应用的重要保障。多模式发射信号、多普勒频率补偿、中频信号采集、双通道数字信号处理、系统复杂时序控制、异常工作状态自修复等设计和实现方法,是在轨信号处理设计与实现方法的核心。本文介绍了海洋二号卫星微波散射计在轨信号处理的要求、结果、设计与实现方法、未来发展等内容。
The HY-2A satellite was first launched in August of 2011 and the microwave scatterometeris one of the main payloads. Design and realization of signal processing onboard is important for Scatterometer of HY-2A Satellite. Multi-mode transmit signal, doppler frequency pre-compensation, IF signal sample, dual-channel digital signal processing, complex timing control of scatterometer and self-repair of exceptional working status, are the core of the design and implementation of signal processing onboard. This paper provides requirements, designs implementationsresults and developments of HY-2A signal processing onboard.
