Abstract
The invention discloses a method for inverting aerogel microphysical characteristics based on a multi-wavelength laser radar. The method comprises the following steps: inputting optical characteristicparameters, and performing normalization processing on the optical characteristic parameter to obtain an optical characteristic parameter; establishing a correlative lookup table between the microphysical characteristic parameter of the aerosol and the multi-wavelength optical characteristic parameter; computing the distance between the input optical characteristic parameter and each individual in the look-up table at an optical characteristic domain, and only reserving K individuals with the minimum distance as the range of a feasible solution; according to a Monte Carlo random sampling theory, generating NMC different search execution orders according to the probability sampling, and orderly solving to obtain NMC alternative solutions; and averaging NMC alternative solutions to obtain afinal inversion result of the aerogel microphysical characteristic parameter. Compared with the prior art, an operation of additionally inputting the auxiliary judgment information is avoided, the execution efficiency is high, and an application demand for laser radar mass data automatic processing can be satisfied.
