Abstract
The invention belongs to computer satellite borne laser radar processing software for extracted forest canopy height and particularly relates to a satellite borne laser radar data processing system. The satellite borne laser radar data processing system is characterized by being formed by an earth scientific laser height measuring system, a system for conducting Gaussian fitting on single wave form and a system for processing data of the same light spot number through an average value method, a maximum value method and a variance method. The earth scientific laser height measuring system is used for converting and extracting radar data of the earth scientific laser height measuring system. The system for conducting the Gaussian fitting on the single wave form is used for conducting the Gaussian fitting on the single wave form. The system for processing data of the same light spot number through the average value method, the maximum value method and the variance method is used for conducting batch processing on any data of the same light spot number through the average value method, the maximum value method and the variance method, characteristic parameters are extracted, and inversion of the tree height is achieved.
