Abstract

The lidar signal component caused by a scattering of the first two orders is described in detail within the framework of the theory of laser sensing taking into account a multiple scattering in the small-angle approximation. Simple formulas are obtained determining a double scattering signal with consideration for lidar geometrical parameters for the media with a strongly extended scattering phase function. The role of diffraction and geometrical optics components of the scattering phase function in a doubly scattered signal is investigated. Estimations are obtained of an accuracy of a considered approximation depending on the field-of-view angle of the receiver at different optical thickness of the scattering layer.
