A Radio Frequency scanner is used to scan radio frequencies nearby to locate drones (UAV) and their operators.

Each drone and transmitter has its own channels and frequency bands. RF-scanners are programmed to scan, analyze and detect the Radio Frequency Bands from the drone (UAV) or the operator.

The RF Scanner is mainly composed of an array antenna, a radio frequency circuit, a multi-channel synchronous receiver, and a GNSS positioning module to realize the detection and discovery of UAVs in a specific frequency range. 

The equipment realizes the detection and early warning of the UAV (remote control) by detecting, identifying and direction finding the up and down remote control signals and data image transmission signals of the UAV. RF-Scanners are passive detection devices and do not actively emit electromagnetic signals.
