The Optimization Design for Microwave Wide Band Blackbody Calibration Target
The microwave wide band blackbody calibration target applied for the microwave radiometers pre-launch calibrations are optimized with its electromagnetic parameteremissivity through the radar cross section (RCS) simulations based on the sub-grid finite difference time domain (FDTD)method. The optimization results indict that round wedge is better than the square one,the best ratio for height to bottom radius is 4:1 for the wide band from 10GHz to 26GHz,and the absorbing materials gradual thickness coating and multilayer coating are helpful to guarantee the uniform distribution of surface temperature while keeping a higher emissivity.
