| Abstract | ||
| A theoretical study carried out to compare a three laser range finder models at different weather conditions depends on the power detector as a function of range R. two widely known conventional range equations are exclusively used when the targets reflects partially the transmitted beam eq. (12), and the targets reflects totally the transmitted beam eq. (13). A new Gaussian beam equation eq. (19) can be applied for all cases partially and totally reflected beam by compare with the two range equation mention above. The Gaussian beam range equation provides correct results and unified the two conventional range equations mention above. The three range equation applied a different atmospheric absorption coefficient, it was found that the three range equation can be used for rain and fog weather case because it gives an approach values, on the other hand for clear sky and very clear sky weather case the Gaussian range equation was the best because it gives a correct results for all values of range R compare with partially and totally range equation. | ||
