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.
