摘要
小卫星大气微波探测仪技术是目前微波遥感技术的一个研究热点。通过研制一台小卫星大气微波探测仪(以下简称大气微波探测仪,英文简称SAMS)并搭载在我国的商业小卫星上,实现对大气温湿度、极端天气和降雨的快速测量。介绍了SAMS的应用方面设计的特点,并结合目前的灵敏度测试数据,分析了在轨应用性能,尤其是在海面气压、大气湿路径延迟反演方面小卫星微波探测仪提供了一种新型灵活的探测手段,同时也对载荷在大气温度和湿度廓线探测常规的探测能力方面也进行了总结和分析,为卫星数据的应用和开发打下基础。
The technology of small satellite atmospheric microwave sounder is currently a research hotspot of microwave remote sensing technology.In this paper,a small Satellite Atmospheric Microwave Sounder(SAMS)has been developed and planned to be carried on commercial small satellites to achieve rapid measurement of atmospheric temperature and humidity profiles,extreme weather and rainfall.This paper introduces the characteristics of SAMS application design,combined with the current sensitivity test data,analyzes the on-orbit application performance,especially provides a new kind of flexible means of detection for sea surface pressure and atmospheric humidity path delay.At the same time,this paper also summarizes and analyzes the conventional detection capabilities of atmospheric temperature and humidity profile retrieval,laying a foundation for the application and development of satellite data.
