| Popis: | An algorithm of weak optical signal processing in lidar measurements under intensive background radiation is described. The algorithm is based on transformation of the Poisson photoelectron flow forming at the output of the photodetector photocathode into a flux with sub-Poisson statistics due to its stochastic-determined “rarefaction.” The quality coefficients of the proposed algorithm are estimated. |
