INFLUENCE OF BACKGROUND RADIANT POWER ON THE SIGNAL-TO-NOISE RATIO OF SPACE-BORNE LASER ALTIMETER
背景辐射功率对星载激光高度计信噪比的影响研究

The Chang'E lunar observation laser altimeter was designed to provide precise altimeter data to accurately map the lunar surface by measuring the time interval between the emission and receiving signal.The relationships of the background radiant power,the multiplication factor,and the optimum signal-to-noise ratio of the receiving system were analyzed.The signal-to-noise ratio experiment for different background radiant power was conducted by using the integrating sphere.The influences of background radiant...
