According to the theory of atmospheric transmission, the atmospheric optical characteristics of a 700 mm laser ranging telescope system are obtained by the inversion of the experimental data through the telescopic multi-elevation method, and a modified model of the ranging equation of laser diffuse radar is proposed. The variation in the Aerosol Optical Depth and atmospheric transmittance under the multi-elevation method, visibility and the oblique transmission atmospheric stratification model are analyzed and discussed. The model is numerically simulated and compared with the measured data of some space debris. The results show that the relative errors of the average echo photon number obtained by the multi-elevation method are less than 15%, and the average relative errors are 4.643% and 7.934%, respectively. The model improves the calculation accuracy of the laser ranging radar equation to a certain extent. |
