Abstract	The paper presents the results of a theoretical analysis of an autodyne UHF geoinformation system (GIS), using a multifunction crystal with N mesaplanar structures as an active element. We considered a continuous mode of GIS operation for polyharmonic generation, with the GIS being radiated by its native reflected radiation at each harmonic. We obtained the basic ratios for autodyne response analysis. Further improvements of autodyne systems are concerned mainly with the introduction of the UHF band and the creation of hybrid ICs for this band. It seems that there is a good prospect in investigating the autodyne characteristics of UHF oscillators, created on the basis of a fundamentally new structure of GIS active element. This is a multifunction Gunn diode with low current drain in the feed network, which is incorporated into the resonant section of a coplanar microstrip transmission line. A conclusion has been made regarding the peculiarities of self-oscillation of such autodyne systems.
