Genetic algorithms (GA) are used to rst intensively estimate the environment from a xed source part of the data. Then, assuming the stationarity of the environment, localization is carried out in the moving source part of the data. Comparison with results obtained previously on the same data set shows that the source range error is reduced by 75%, while the source depth error is reduced by approximatelly 50%. Further, using a band of 20 Hz instead of a single frequency conducts to more stable source location estimantes.engNorth Elba data setEnvironmental focusingconference objecthttp://dx.doi.org/10.1109/OCEANS.1999.800246
