神舟4号主载荷——多模态微波遥感器

SZ-4 Main Payload-Multi-Mode Microwave Remote Sensor

多模态微波遥感器作为神舟4号主载荷是我国第一次进入太空的微波遥感器,是一部集高度、散射计和辐射计为一体,具有综合观测能力的微波遥感器。在神舟4号飞船在轨飞行实验期间,取得了大量的有效科学数据,在轨实验获得成功。从多模态微波遥感器的研制要求出发,列出了系统的主要指标,介绍了多模态微波遥感器的工作原理、系统组成、运行控制模式和系统验证试验,总结了在轨运行情况和数据处理结果,给出了实验结论。

SZ-4 main payload-multi-mode microwave remote sensor is the first spaceborne microwave remote sensor in China. It is composed of an altimeter, a scatterometer and radiometers. In the system, the altimetry, scatterometry and radiometry functions are integrated technically. A lot of data are acquired during SZ-4 orbital experiments. The orbital experiments are successful. In the paper, the main characteristics are listed based on development requirements. The principle, block diagram, control system and system tests of multi-mode microwave remote sensor are introduced. The orbital experiments are summarized and conclusions are put forward.
