新型地基大气廓线微波探测仪及其参数反演

The new design of improved ground-based atmospheric microwave sounder was presented.It has 7 channels in v-band (50~59 GHz) to retrieve temperature profiles and 7 channels in k-band (22~31 GHz) to retrieve humidity profiles.Different from MP3000,it adopts independent reflectors and direct-detect type,so it has simple structure,high spatial resolution,and low maintenance cost and small size.According to the radiometric transfer equation and radiosonde datasets,the weighting functions and brightness temperatures have been derived.Using back-propagation neural network,it can retrieve atmospheric temperature profiles.The results show that the prototype of ground-based atmospheric microwave sounder satisfies the requirements of spatial and temporal
