Numerical Analysis on the Emissivity Determination of Microwave Calibration Targets by Scattering Measurements
The calibration target is a vital instrument for calibrating the space-borne microwave radiometers.The calibration target is designed to be with a high emissivity close to 1,and its emissivity must be accurately determined before its practical usage.The emissivity of calibration target can be determined in the way of reflectivity measurement,in which the overall reflectivity has to be inferred based on the measured scattering in limited angular region.There are typical two setups in measuring the emissivity,one is the monostatic measurement and the other is the bi-static measurement.In this work,the authors discuss the remaining issues in the two measurement configurations,and report their recent progresses.
