Accuracy and precision studies for range-only underwater target tracking in shallow waters

摘要

This paper provides a study on the precision, and the accuracy, of an underwater target tracking system with acoustic waves, using range-only and single-beacon methods, in shallow waters environments. For this study, different field tests have been realized in the OBSEA test site, a well-known and monitored area at 4 km from the coast and at 20 meters of depth, in the Mediterranean Sea (Barcelona). The tests have been conducted using two acoustic underwater modems from the company LinkQuest Inc. Moreover, the autonomous underwater vehicle developed by the Universitat Politecnica de Catalunya (called Guanay II) have also used to perform the tests.
