Antenna Far-field Test System and Signal Processing Based on UAV Platform

In antenna performance testing, near-field testing is less reliable than far-field testing due to various factors. This system uses the UAV to carry an omnidirectional antenna that matches the antenna to be tested. When drone moves in a circle around the antenna, the antenna under test receives the signal from the transmitting antenna and transmits the signal to the data acquisition board. The data acquisition board transmits the data to the PC in real time through the gigabit network port, and processes the received data on the PC and draws the signal time domain diagram and frequency domain diagram. The directional diagram also requires the GPS coordinates of the drone's flight. This system provides great convenience for the tester.
