Analysis results of autodyne signals of the double-diode oscillator, which is under influence of the proper reflected emission from the moving object, are presented. The analysis is performed on the base of the autodyne mathematical model presented in the form of a system of two mutually-locked partial oscillators under condition of strong mutual coupling. Peculiarities of signal formation are considered for various parameters of partial oscillators and coupling conditions. Experimental data are obtained for the 8mm-range Gunn double-diode oscillator of the flange type.References
