About an energy potential of autodynes

The expressions for calculating the noise characteristics and energy potential of an autodyne system taking into account both internal fluctuations of an oscillator active element and real power supply noises of a microwave oscillator were found. Calculations made on the example of a Gunn diode oscillator showed that the autodyne potential on case of detecting signal in the power circuit of oscillator is significantly lower than in case of detecting signals by changing the frequency and amplitude of oscillations.
