Abstract :
The authors show that the superresolution technique can be used for antenna measurements and scattering studies. They describe experimental results of antenna measurements and simulation results of electromagnetic scattering mechanism extraction using MUSIC. It is shown that, using MUSIC, one can isolate the individual scattering centers and can obtain each diffraction coefficient using much narrower bandwidth data than the FFT (fast Fourier transform) and gating techniques.<>
