Analysis of laser detection range of underwater objects

摘要

Paper presents selected issues on laser systems for detection and location of underwater objects. Specific influencing factors, as hydro-meteorological as well as environmental conditions, are also discussed. For the assumed parameters of proposed laser rangefinder model, on the basis of additional experimental results, an analysis and numerical calculations of background noise power, signal power and signal to noise ratio at the output of receiver have been performed. Thereby, the effective detection ranges of underwater objects under various meteorological conditions in different seasons have been obtained.
