Abstract:
The method of lidar return representation with the account for multiple scattering as a component of the total flux into the backward looking hemisphere at unlimitedly increasing field-of-view angle of the reception is considered in terms of small-angle approximation. This approach allows us to treat the interference due to multiply scattered radiation as useful components of a signal, which can be used in the interpretation of lidar measurement data. Based on the asymptotic properties of the lidar return at large field-of-view angles of reception, the possibility is demonstrated to simplify the lidar equation by replacement of the scattering phase function for one parameter - the particles' efficient size. Based on this new representation, the iteration method for solving the lidar equation is developed.
