As Light Detection and Ranging （LiDAR） technology develops, the small-footprint full-waveform LiDAR data processing and its application have been hot topics in related fields in past years. The processing flow for waveform decomposition was introduced with the focus on the components and data feature of airborne small-footprint full-waveform LiDAR, and it application to forestry was also summarized. Based on the current research status, the paper discussed the theory and methods for waveform decomposition and forest structural parameter extraction. In the end, the limitations of data processing using small-footprint full- waveform LiDAR waveform were described, and its application to forestry is also prospected.
