In this work the decision technique of the lidar equations concerning a profile of an aerosol extinction coefficient is developed. On the basis of this technique the algorithm of calculation of a profile of aerosol extinction coefficient from the backscattered signal is builded. Possibilities of application of Digital Signal Processing (DSP) methods for reduction of an error of calculations at various stages of the builded algorithm are analysed. Application of filters exponential average, a sliding average, lowpass FIR and their combinations is considered. Taking into account possibilities of application of DSP methods the developed algorithm is corrected for work with noised signals. On the basis of the corrected algorithm the program for LabView environment on calculation of a profile of aerosol extinction coefficient is developed. Results of work of the program with test model noised the backscattered signal and with the data taken with real lidar of a locator of aerosol formations in atmosphere are resulted.
