Abstract

During KHz daylight tracking, the KHz laser beam is high repetition frequency and low pulse energy. And it is difficult to maintain receive and transmit path parallel. This paper introduces a new method of daylight visibility of KHz laser beam real-time. It resolved the problem of too much background noise at daylight and used the high sensitivity CCD to require the daylight KHz laser beam imaging real-time. It applied the spectrum filtering technology, exposure superposition, changing exposure time and image processing technology in the experiment. The clear backscatter image of KHz laser beam had been required real-time. It has important significance to enhance daylight KHz satellite laser ranging (SLR) system in detecting ability.
