中文摘要
当前世界主要国家都在探索地球静止轨道气象卫星以提高对极端气候实时预报的能力。但是相对于红外与光学,微波波长太长,为满足所需空间分辨率的天线口径太大,如何在地球静止轨道这么高的轨道上实现所要求的空间分辨率是一个世界性难题。.本项目针对地球静止轨道大气微波遥感的高空间分辨率要求,提出基于阵列平移复用的镜像综合孔径辐射测量方法。该方法是在已研究的常规镜像综合孔径测量方法基础上,创新性地通过平移小型阵列实现阵列复用,改善常规镜像综合孔径转移矩阵秩亏缺问题,同时以较少天线单元实现高空间分辨率来降低星载应用风险。围绕阵列平移复用优化问题,开展面向灵敏度最优的驻留式平移复用策略、面向系统复杂度最低的天线排列优化、镜像综合孔径系统平移复用误差分析等研究,解决驻留式平移复用优化模型、天线排列优化模型、平移复用误差模型等关键科学问题,并开展仿真与样机实验验证,为该方法在大气微波遥感领域的应用奠定技术基础。
英文摘要
At present, major countries in the world are exploring geostationary orbiting meteorological satellites to improve the ability of real-time prediction of extreme climate. However, due to the relatively long wavelength of microwave in comparison with infrared and visible, the antenna aperture must be very large to meet the required spatial resolution. How to achieve the required spatial resolution on the geostationary orbit is a worldwide problem. .In order to meet the requirement of high spatial resolution for geostationary orbiting microwave atmospheric sounding, mirrored aperture synthesis radiometry based on array translation multiplexing is proposed. Based on conventional mirrored aperture synthesis, array translation multiplexing is innovatively proposed to improve the rank defect of transform matrix, and a small array can be adopted to achieve high spatial resolution to reduce the risk of satellite application. Aiming at the optimization of array multiplexing, the optimal sensitivity-oriented resident translation multiplexing strategy, the least complexity-oriented antenna arrangement optimization, and the error analysis caused by array multiplexing will be studied. And the key problems will be investigated, such as the optimization model of resident translation multiplexing, the optimization model of antenna arrangement, and the error model referring to array translation multiplexing. Numerical simulations and prototype experiments will be carried out to demonstrate the validity of the method. The study can provide a technical foundation for the application of mirrored synthetic aperture radiometry in the field of microwave atmospheric sounding.
