Abstract


Satellite Laser Ranging' dissertation">Laser Ranging (SLR) is a technical method to study many subjects such as geodynamics, atmospheric dynamics and geophysics.The aim of this paper is to try to observe the satellite with no retroreflector based on SLR. Based mainly on theories and experiments, we forecast the dependence of the distance of the satellite that can be observed on the power of the laser. Of course, the dependence is related to the beam parameter of the laser.According to the conventional laser ranging, the theoretical derivation, experimental methods and the forecasted method of Diffuse Reflection Laser Ranging are presented in this paper. Main items of the work are listed as below:1. Combining SLR eqaution and parameter, a new formula of Diffuse Reflection Satellite Laser Ranging is deduced. The parameters in the formula are also deduced in detail.2. Using our experimentation equipments, laboratory experiments are made and two parameters thereinto are testified. According to experimentation data, theories are revised and hypotheses and insufficiencies are presented.3. The experiment computer data—processing program is writed and experimentation data are analysed and fitted using the program.Taking theories and experiments into account, my work is only a scheme. Simplifies made in the theoretical derivation and experiments are not entirely satisfying. We think that Diffuse Reflection Satellite Laser Ranging will become a realy with the development of experimentation equipments and following work.
