Summary

 
Object and purpose of research. The object of this research study is a physical phenomenon of lidar observation of hydrophysical disturbances from an object moving underwater confirmed by the scientific discovery registered with Russian Academy of Natural Sciences (RANS). The purpose is to briefly present the phenomenon essence and to validate the feasibility of underwater monitoring system involving lidars.
Subject matter and methods.The work materials is the phenomenon description and publications confirming its reliability. The feasibility of underwater monitoring system employing lidars is validated by model representation of this system as a group of distributed fixed lidars, which record time instants when a moving underwater object is passing by. The navigation task of locating its coordinates and parameters of motion is solved.
Main results. The results demonstrate exact solutions to the problem implemented in MATLAB programming system, which confirms that the model is adequate and its software implementation is correct.
Conclusion. The purpose of the work to examine the feasibility of lidar underwater monitoring system is achieved. The new scientific results are the problem formulation and the method of solving a navigation problem to find coordinates and parameters of motion from lidar-detected instants of hydrophysical disturbances. A hypothetical lidar-based monitoring system, if verified experimentally that lidars are sufficiently long-range instruments, is a promising idea.
