Abstract
For satellite laser ranging(SLR) with high repetition rate, the interference of atmospheric backscattering on the echo receiving has been more serious by the increase of measuring rate, and has become one of the key factors which restrict the maximal working frequency of SLR technology. According to the atmospheric scattering radar detection equation, the received optical power of atmospheric backscattering from a certain distance was analyzed. Based on the platform of bi-static SLR system in SHAO, the rationality of theory was verified by interference experiment of atmospheric backscattering. According to the theory, making clear production mechanism of backscattering interference, backscattering avoiding methods on the basis of controlling laser emitting epoch were presented. With a module for outputting laser fire signal integrated into range-gate generating circuit with high repetition rate, and the control of the laser firing delayed by judging the existence of backscattering in real time, the backscatter auto avoiding circuit was finally completed based on FPGA. Now it has been successfully applied in the routine SLR measurement of SHAO, the average fire frequency reduction rate has been lower than 2% for most important satellites such as Lageos, and will has a very good propagation and application value.
