Abstract:
This scientific article presents a block diagram of a two-channel radio
direction finder that effectively uses the phase method to determine the
direction of the signal source. The main attention is paid to the mathematical
model of the formation of the cardioid radiation pattern of biconical
antennas, which have unique directivity characteristics. These features
significantly affect the accuracy and reliability of the bearing determination
process. The developed algorithm aims to accurately determine the direction
of motion of an unmanned aerial vehicle, especially in the context of a twochannel radio receiver and a five-element antenna system. This antenna
system provides unique capabilities for increased resolution and directional
accuracy. The article also touches on the issue of software implementation of
the developed algorithm, which is aimed at increasing the number of
generated bearing estimates in conditions of limited time for observing an
unmanned aerial vehicle. Thus, the proposed method is of interest in the
field of precision direction finding in the context of small unmanned
vehicles.
