Abstract:

Traditional multi-rotor UAV tracking detection system has strong data dynamics and large variables in tracking data detection, which affects the overall effect of tracking detection. Therefore, the design of tracking detection system for multi-rotor UAV based on discrete Fourier transform is proposed. The design system is mainly divided into two parts: detection hardware and execution program. Among them, the detection hardware is designed with RX5403 rotor data sensor, AD4431 data acquisition controller, data logic rheostat and signal component controller module, and the signal component controller is realized by each module. Modulation output; the software part uses the discrete algorithm to design the tracking data discrete processing program, and uses the discrete Fourier transform to close the loop in the tracking data transmission channel, and designs the tracking data Fourier transform output program to achieve multi-rotor Man-machine tracking detection system design. The comparison of experimental data shows that the design system has the function of optimizing the recognition accuracy of multi-rotor UAV tracking data and improving the overall tracking efficiency of the system.
