Multiple-scattering Lidar Equation
註釋This paper derives a multiple-scattering lidar (laser infrared radar) equation from a phenomenological representation of the scattering processes. The contributions are separated into the unscattered, singly scattered, and multiply scattered illuminations of the scattering volume, a single backscattering reflection from that volume, and the unscattered & multiply scattered propagation back to the receiver. The equation is obtained in the form of analytic expressions that explicitly show the signal dependence on the extinction coefficient, the effective particle size, the range, & the receiver field of view. Comparisons are made with Monte Carlo calculations & published laboratory measurements. Results of numerical simulations are presented to demonstrate whether measurements made at three or more fields of view can be inverted to solve for the extinction coefficient & the effective particle radius.
