Generalized Model of Antenna System for Radio Monitoring Stations

This paper presents the construction of a generalized model of the antenna system for radio monitoring stations. The generalized structural diagram of the antenna consists of the following main parts: an antenna array and a block of amplification and frequency conversion of signals, which includes a measuring transducer, a two-level linear converter, a block of nonlinear transformations, a signal identification device, a processor and a device for indication and registration of signals. In the model, the number of variable informative voltages was limited to ensure simple functional connections between voltages in the signal processing circuit. This makes it possible to simplify the determination of the accuracy characteristics of the measuring antenna system. The dependencies of the indicator voltages were built, according to which the antenna is tuned in the direction of arrival of the signal under investigation.
