Paper Abstract

There are some effects of atmospheric turbulence on the laser radar, which include the transmitter beam spread, the target plane scintillation and the target return beam spread. When the turbulent layer is close to the target, there will not be essentially transmitter and the target return beam spread. However, there is always the turbulence-induced target scintillation which will produces a notable impact on laser radar image. This paper mainly studies the turbulence-induced target scintillation. A model of atmospheric propagation has been set up with Huggens-Fresnel principle. Meanwhile we have set up a computer simulating system with the principle of the sample statistics. The results shown that the clarity of the target was affected seriously by atmospheric turbulence. Especially when the scintillation is saturated or nearly saturated, the target can not be seen. To improve the image quality, we used the measurements of the more-frame overage and the range gating. For glint target and speckle target, this two methods were effective.
