A mathematical model has been developed for a double-diode autodyne oscillator affected by the proper reradiation. The model represents two mutually-synchronized partial oscillators with time delayed coupling between them. It is possible for studying peculiarities of autodyne amplitude variations of the partial oscillators, autodyne variations of frequency and phase difference and, also, in the power...
Calculations of phase, frequency and amplitude characteristics are performed as well as the output signal, which is registered in the power supply circuit of the autodyne oscillator with linear FM of radiation are carried out. Calculations are performed at different values of feedback parameter. At that, dependences of appropriate noise levels as functions of distance to reflector are given. The phenomenon...
The autodyne sensor description on Gunn diode of 8-mm wave-length intended for detection of path occupation and the caps of the obstacle device for transport vehicles at guarded and non-guarded railway crossings is discussed.
