A Practical Microwave Radiometer Design and Atmosphere Remote Sensing

The principles and related concepts and methods of atmosphere remote sensing by using microwave radiometers are explained as clear as possible in this book. Practical design tools are presented as well, including: A. The method and procedure for designing and analyzing a microwave radiometer are presented through an example design of a V band microwave radiometer, and the design is down to schematic level including design of radiometer microwave front end and radiometer controller; B. A lot of MATLAB programs are presented in this book for designing and simulating radiometers, including programs to calculate atmosphere microwave absorption coefficients, programs to execute the tipping curve calibration, and programs to retrieve atmosphere temperature profile; C. The Backus-Gilbert method has been applied successfully for resolving the inverse problem of radiation transfer equation and a full MATLAB program package for implementing the Backus-Gilbert algorithm is presented in this book. D. An example design of a V-band radiometer by using substrate technology is presented as well. E. Finally, almost every aspects of the two point calibration method are analyzed and a real time calibration procedure (doing calibration while carrying out measurement) is proposed for noise adding radiometers.
