4 Lidar Equations laser pulse energy, in photons LIDAR transmitting path optical efficiency (from laser source to telescope) LIDAR receiving path optical efficiency due to filters' contribution, interference (IF) filter and Capacity Stabilized Etalon (CSE) filter LIDAR receiving path optical efficiency from telescope to filters on-ground LIDAR reflectivity across-track angle to nadir [deg] telescope area [m 2 ] spacecraft altitude [m] total column atmospheric transmission due to aerosol and molecular backscattering, where α is the aerosols backscattering coefficient and β the molecular scattering coefficient The terms of the expression have the following meaning:

5 Background Photons The meaning of the terms is the following: albedo of reflecting surface Sun spectral irradiance at 1 AU [W·m -2 ·sr -1 ·nm -1 ] telescope field of view [rad] Sun incident angle [deg], depending on the orbit parameters i.e. LTDN TFOV

6 Total Noise The total number of background photoelectrons at instrument output is a combination of the solar background and detector noise as shown in the following equation: where P B is the solar background power [W] F is the excess noise factor of the detector NEP is the noise equivalent power of the detector after amplification [W·Hz -0.5 ] QE is the detector quantum efficiency Therefore, the total noise is

7 Lidar Signal Photons and Probabilities Wavelength is 1064nm Altitude is 300km Resolution is 200 by 200 pixels Laser pulse energy(J)=1 Surface Albedo=1 Copyright © 2008 Lidar Technologies Limited
