Parameters and Characteristics of a Transistor Autodyne Transceiver in Asynchronous Reception of Request Signals from an Atmospheric Radiosonde System

Based on the developed mathematical model of a transistor autodyne transceiver (APP) designed for a promising atmospheric radar sensing system, calculations and analysis of the APP’s parameters and characteristics have been performed in asynchronous mode of receiving radar request radio pulses when the frequency of the received signal is outside the APP’s synchronization band. Noise and energy parameters and characteristics are investigated when approximating the impedance characteristic of the active element by the biquadrate parabola. Calculations of the range of the system have also been performed both via the «requester — responder» channel and the «responder–requester» return channel. Practical conclusions necessary for the development of this system are drawn.
