Abstract

Wide use of computing engineering and radiolocation and communication systems has promoted development of new methods and means of receiving and processing signals based on discrete transformations in orthogonal function classes. A technical realization of the devices which use basic function systems to describe two-dimensional signals in quasi-optics becomes a simpler one when using orthogonality properties of Gaussian wave beams. A multimode two-mirror open resonator (OR) (of Fabry-Perot type) with an input partially transparent reflector is an ideal tool for orthogonal transformation of fields in the millimeter- wave region. The paper reveals the concept, gives assessments to the spectral methods of recording and analyzing an electromagnetic SHF-field amplitude-phase structure and describes possible application methods.
