摘要: 海洋环境要素探测多包含海面温度、海水盐度、海冰厚度以及有效波高等多个方面,海洋环境要素探测多采用微波辐射计实现。高分辨率和高灵敏度的辐射计一般信号带宽宽、通道多,多采用混合体制,分布式分级实施策略进行采集、相关和反演处理。针对项目需求,重点介绍了海洋环境要素探测仪处理器的多通道采集处理单元的设计和实现,并结合微波辐射计系统对采集处理单元进行测试验证,最后给出了测试结果。结果表明,所设计的多通道采集处理单元可对400 MHz的宽带信号进行正确采集处理,辅助数字相关器实现干涉处理,完成反演成像参数的提取。

Abstract: The detection of marine environment elements include surface temperature,salinity,ice thickness,significant wave height etc.Usually,marine environment elements are detected by microwave radiometer.High resolution and sensitivity radiometer normally has wide signal bandwidth,multi-channel,hybrid system for acquisition,correlation and inversion processing with distributed and classification strategy.According to the project requirements,the design and realization of detector with multi-channel acquisition and processing unit for marine environment elements are highlighted.The test and verification are combined with radiometer system and acquisition and processing unit.The results show that the designed multi-channel acquisition and processing unit can correctly acquire and process the broadband signal at 400 MHz,assist the digital correlator to realize the interference processing,and complete the extraction of inversion imaging parameters.

Key words: microwave radiometer, acquisition and preprocessing, interferometric processing, sea surface temperature, multichannel
