Synthesis of improved-quality images in the millimetre wavelength range

The possibilities of quasi-optical imaging of concealed objects illuminated by millimetre wavelength range radiation are demonstrated both theoretically and experimentally. The influence of the spatial Gibbs effect and of other destructive factors on the quality of the obtained images is studied. A method is proposed for synthesising improved-quality images with enhanced information content in the millimetre wavelength range. It is shown that the theoretical and experimental results are in good agreement.
