Embodiment Construction
[0022] The present invention is further analyzed below in conjunction with specific examples.
[0023] The basic lidar equation is
[0024] P ( r ) = CY ( r ) A r 2 β ( r ) T 2 ( r ) , - - - ( 2 )
[0025] In the formula, P(r) represents the intensity of the echo signal, C represents the system constant, including the energy of the emitted laser, the transmittance of the system, etc., Y(r) is the overlap factor between the emitted laser and the field of view of the telescope, and β(r) represents Backscatter coefficient, T 2 (r) refers to the atmospheric extinc...
