Embodiment 1
[0016] refer to figure 2 . The UAV uses an omnidirectional antenna suspended under the UAV. The ground UAV measurement and control terminal controls the omnidirectional antenna of the UAV’s hovering height and position and the UAV auxiliary antenna as an auxiliary test terminal. The ground control terminal controls the UAV. Human-machine transmission frequency and signal strength, test the direction diagram of the airborne antenna communication of the UAV to be tested.
[0017] The airborne antenna to be tested is installed on the airborne platform, and the test turntable rotates around the axis. The airborne antenna to be tested is connected to the vector grid. It moves on a circle centered on the rotation axis of the table. The ground UAV measurement and control terminal controls the hovering height and position of the UAV. The ground station receives the signals emitted by the auxiliary antenna of the UAV auxiliary terminal at various angles, and the ground station receiv...
Embodiment 2
[0021] refer to image 3 . The unmanned aerial vehicle adopts the way of flying around, and the airborne test terminal of the ground station adopts a fixed airborne antenna to be tested. According to the radius satisfying the far-field condition, the drone is set to fly around at a fixed radius with the turntable as the center. Man-machine flight height, auxiliary antenna transmission frequency and transmission signal strength, while controlling the drone loaded with signal source to fly around the receiving antenna, and by adjusting the flight height and flight radius of the drone, the antenna pattern test of the whole antenna in different angles is realized .
