Abstract

In the paper

theoretical model of the effect of mutual coupling between antenna elements on the imaging of synthetic aperture radiometer (SARad) is established.The effect of mutual coupling on the resolution of SARad is analyzed.An analytical expression for the calibration of mutual coupling is presented.On the basis of theoretical results

a scheme for the calibration of SARad is proposed.Numerical simulations show the validity of the proposed method.
