Abstract

The development of all-fiber Doppler wind lidar has garnered significant interest in mobile wind detection due to its compact design and reliability. We have developed a mobile Doppler wind lidar (MDWL) suitable for individual equipment applications. Based on the theoretical model of the signal-to-noise ratio (SNR) function, we determine the system parameters to strike a balance between detection capability and compactness, specifically tailored for portable lidar instruments. The detection range of more than 2km is achieved with a pulse energy of 20μJ and a pulse width of 400ns. We integrated two wind field inversion methods—VAD scanning detection and forward horizontal detection—into a proposed intelligent operation algorithm. Through time-frequency analysis, we successfully measured the precise distance to hard targets and obtained wind field results with a single lidar, highlighting the potential for multifaceted information detection. The experiments in urban areas further validate the effectiveness of wind detection methods.
