Abstract

The principles of design, problems of engineering realization, some results of first applications of two- frequency scanning Linear Frequency Modulation (LFM) lidars are discussed in the present paper. Basic method of transformation of one-frequency radiation into two-frequency one is described. The requirements to parameters of probing radiation, dept of modulation, band of scanning and modulating frequencies, laws of scanning and modulation are defined, spectral and temporal resolution are calculated. The different variants of two-frequency scanning LFM lidars with direct and heterodyne detection are examined, in particular: with probing frequencies being located inside absorption line; with the first probing frequency inside the absorption line and the second one outside it. The block- scheme of a two-frequency scanning LFM lidar is described, and parameter requirements of two-frequency radiators and lidar photoreceivers are discussed.
