The problems of working out the IR-CW-LFM-lidar with transformation of one frequency laser radiation into two frequency and tuning probability are considered. Comparative analysis results for characteristics of two frequency laser radiators put into differential IR-CW- LFM-lidars are given. The perspectivity for amplitude-phase electrooptical devices developmeni is shown. Their scheme decisions are considered. Theoretical and experimental investigation results of transformation parameters effect on purity of radiator output spectrum, as the main function, which determines the metrological characteristics of IR-CW-LFM-lidar on the whole are presented. The possibilities of IR-CW-LFM-lidars with frequency transformation realizing different ways of gas remote sensing are estimated. The experimental setup's structural scheme is presented. Keywords: remote sensing, infrared lidar, linear frequency modulation, electrooptical frequency transformation
