Presented and tested digitally a method for improvement of quality of radio thermal images in millimeter-wave band, based on the aprioristic information about statistical characteristics of a similar class objects’ spectra and known receiver antenna transfer function. The method realization is a filtration of false overshoots in spatial spectrum of the radio thermal image to be improved. The spatial resolution is shown to be increased significantly depending on noise level and accuracy of transfer function prescription.
