Scattering from Periodic Cone Structure Array
The scattering patterns of cone array structures with absorbing material,commonly used for calibration targets of microwave radiometers are numerically studied using the finite-finite difference time domain(FDTD)method.The bi-static scattering far-field patterns are calculated and integrated to obtain the reflectivity of the structures,which provide the emissivity information of the corresponding structures.The scattering patterns from different cone structures made by PEC,absorbing material coated PEC and absorbing bulk material are simulated with irradiating sources of plane wave and Gaussian beam.A method of calibration target performance measurement is designed based on the analysis of the simulation results.
