Utilizes TDOA four-station positioning detection to obtain UAV coordinate information

Unmanned aerial vehicle (UAV) signal localization is achieved through a Time Difference of Arrival (TDOA) network composed of small outdoor monitoring receivers. Typically, at least four mobile or portable monitoring stations need to be deployed with a spacing between stations ranging from 300 meters to 1 kilometer. Each station is capable of both conventional signal monitoring tasks and TDOA localization.

TDOA localization is a method that utilizes time differences for positioning. By measuring the time it takes for a signal to reach each monitoring station, the distance from the signal source to each station can be determined. By creating circles with the monitoring stations as centers and the measured distances as radii, the position of the signal can be determined. Absolute time measurement is generally challenging; however, by comparing the absolute time differences of signal arrival at each monitoring station, hyperbolas can be constructed with the monitoring stations as foci and the time differences as the major axis. The intersection points of these hyperbolas represent the signal's position.
