Abstract:
    The invention discloses a laser radar for detecting the atmosphere turbulence via a positioning sensitive detector, which relates to the refractive index structure constant profile Cn2 and atmospheric coherence length r0 of the atmosphere turbulence. In the invention, the laser radar takes a pulsed laser as the emission source, and the dual-aperture Rayleigh scattering echo received by the telescopes is focused on the positioning sensitive detector through the reflection prism, and the profile Cn2 and atmospheric coherence length r0 are obtained by micro-processing after the positioning signals are transferred to the digital signals via A/D processor.
