Experimental Studies with Software Defined Radio Receivers of Aerial Objects On-Board Systems Signals

The paper proposes experimental studies with Software Defined Radio receivers of aerial objects onboard systems signals. It is established that the signals of the following channels are additional sources of signals, for example, of unmanned aerial vehicles: command, telemetric, issuance of targeted information, manual control, satellite navigation. Experimental studies were conducted and signal spectrograms of signals were obtained. The RTL 820T2 model was chosen as the Software Defined Radio receiver. For an aerial object coordinates determining that emits the signals, we will use the network of Software Defined Radio receivers. So, the resulting measurement error when using the radar and the Software Defined Radio network of receivers is determined. We can see that the use of the Software Defined Radio network of receivers will increase the overall accuracy of determining the coordinates of an aerial object.
