Laser sensing theory with multiple scattering taken into account in the small-angle approximation is used to separate out the component of the lidar signal associated with the first two orders of scattering. For media with a strongly forward-peaked scattering phase function, simple formulas for the doubly scattered signal which take account of the geometrical parameters of the lidar are derived. The role of the diffraction component and the geometrical-optics component of the scattering phase function in the doubly scattered signal is examined. The accuracy of this approximation is estimated as a function of the detector field of view for different optical depths of the scattering layer.
