The unmanned aerial vehicle system comprises an unmanned aerial vehicle and a ground base station in wireless communication with the unmanned aerial vehicle, and an ultrasonic transmitting mechanism and an ultrasonic receiving device are arranged at the bottom of the unmanned aerial vehicle; the ultrasonic transmitting mechanism comprises an auxiliary transmitting device and a transmitter which are connected to a transmitting support, the transmitter is movably connected with the transmitting support through a rotating table, and the ultrasonic receiving device comprises at least two sets of simulated external ears which are connected to a receiving support and arranged side by side. Each group of simulated external lugs is connected to the corresponding six-degree-of-freedom platform through an external lug bracket, and each group of six-degree-of-freedom platform is positioned at the top of the platform bracket. Through the transmitting device and the receiving device for simulating the bat, the vibration and sound production of the nostrils of the bat are simulated to generate ultrasonic signals and the external ears of the bat are simulated to receive the ultrasonic signals, a complete image is generated through an ultrasonic image display principle, and the accuracy of face recognition is improved when the unmanned aerial vehicle is in a dark environment.
