AbstractThe laser beam, which is eradiated by the active detecting system in the detecting process, will come in for scattering in multi-directions by atmospheric molecules and aerosol particles. The back-scattering transmits in the reverse direction and gets in the receiving system, which will bring severe interference to the target detecting, sometimes may even make the detector get into saturation. This paper built a physical model of the atmosphere back-scattering in the active detecting system, and analyzed the impact of several factors such as geometrically configure of the system ,LOS angle deflection, the detecting distance, the intensity of the noisy light, and analyzed the interfering ability of the back-scattering light to the target echo light and then validated the illation of the interfering ability by a short distance experiment indoor. The experiment get an appropriate result with the illation, which can use for reference for the design of system involving the transmitting of the laser light in the atmosphere such as laser active detecting, range measurement with laser and so on. © 2014 SPIE.; The laser beam, which is eradiated by the active detecting system in the detecting process, will come in for scattering in multi-directions by atmospheric molecules and aerosol particles.
