Abstract: A UAV having a radar-guided landing function that helps the UAV to land on a landing station is disclosed. The UAV uses a GPS transceiving unit's positioning, and receives a flight path from an external source through a control unit to advance toward the landing station. When the UAV approaches a landing station, the control unit receives an activation signal and activates a landing radar to continuously transmit a frequency sweeping radar wave. When the frequency sweeping radar wave reaches the landing station, a reflected radar wave is generated, so that the landing radar receives the reflected radar wave and transmits it to the control unit. The control unit performs computation based on data related to the reflected radar wave and accordingly controls the UAV to land on the landing station.
