The intensity data of the echo record the information about the radiometric characteristics of the object and can be effectively used in the object extraction and other remote sensing quantitative applications. Therefore the study on radiometric characteristics of intensity data has become a new hot spot in the field of LiDAR. The radar equation is studied on the basis of the theoretical derivation of radiation transmission mechanism, and the radiation properties and key influences of intensity data are systematically discussed and analyzed. Finally, these theories are verified and discussed by using the experimental platform of LiDAR system. The results and conclusions provide the necessary theoretical basis and technical support for radiometric calibration, object classification, and other quantitative applications of the waveform data.
