For statistical estimation of the potential possibilities of the lidar with matrix photodetector placed on board an aircraft, the nonstationary equation of laser sensing of a complex multicomponent sea water medium is solved by the Monte Carlo method. The lidar return power is estimated for various optical sea water characteristics in the presence of solar background radiation. For clear waters and brightness of external background illumination of 50, 1, and 10–3 W/(m2⋅μm⋅sr), the signal/noise ratio (SNR) exceeds 10 to water depths h = 45–50 m. For coastal waters, SNR ≥ 10 for h = 17–24 m, whereas for turbid sea waters, SNR ≥ 10 only to depths h = 8–12 m. Results of statistical simulation have shown that the lidar system with optimal parameters can be used for water sensing to depths of 50 m.
