Two designs of the laser radar system operating on the basis of the backscatter amplification effect (BSA) are suggested. The system is, in fact, a micro-pulse aerosol lidar with two receiving channels, one of which records an increase in the echo signal on the laser beam axis with an increase in the atmospheric turbulence intensity. The BSA effect has place in a narrow spatial region around the laser beam axis; so, the receiver aperture should be small enough. The creation of the turbulent lidar became possible with the advent of compact pulsed lasers with pulse energies lower then mJ and pulse repetition rates of several kHz. The lidar is intended for continuous long-term unattended operation. It is eye safe. Two schemes of the turbulent lidar on the basis of an afocal Mersenne telescope (mirror collimator) are suggested. BSA-2 and BSA-3 turbulent lidars are described. On the basis of Vorob’ev’s approximation for statistically homogeneous turbulent environment, an algorithm is suggested for retrieval of the structure parameter of optical turbulence Cn2 from lidar data.
