The problem is that the signal sent by some of the sonars is reected not by the desiredobject(s), but by some auxiliary object and thus, the values measured by these sensors are drasticallydierent from the distance to the desired object. To solve this problem, currently probabilistic methodsare used; however, since we do not know the exact probability distributions, these methods may missthe actual location of the object. There exist interval-based methods which provide guaranteed (reliable)bounds on the object's location, but these methods sometimes require too much computation time. Inthis paper, we propose a new faster algorithm for reliable localization of underwater objects. %G English %L hal-01196433 %U https://hal.science/hal-01196433 %~ UNIV-BREST %~ INSTITUT-TELECOM %~ ENSTA-BRETAGNE %~ CNRS %~ UNIV-UBS %~ ENSTA-BRETAGNE-STIC %~ ENIB %~ LAB-STICC %~ TDS-MACS %~ INSTITUTS-TELECOM
