Abstract

In the present paper the target restoration of range-gated imaging in scattering environments is investigated. The degradation matrix of the laser beam and the scattering mediums is estimated by a specified backscattering image from the atmospheric scattering mediums. A variational model is proposed to eliminate the influence of the degradation matrix. Experiments of range-gated imaging are carried out to capture the images of the targets and scattering mediums. The proposed method is performed to restore the target images based on the backscatter images from the scattering mediums. The experimental results show the proposed variational method is effective to eliminate the effects of nonuniformity of the laser beam and smoke and to obtain the correct reflectivity distribution of the target, as well as smoothing the noise.
