Buried spherical shells localization in presence of phase uncertainties

摘要: Buried object localization in presence of sensor phase errors is presented this study. Phase are introduced by the moving array from their original positions during experiment which gives an erroneous localization. To solve problem, objective function defined using exact solution scattered acoustic field MUSIC method. The DIRECT algorithm (DIviding RECTangles) used to seek minimum function. method provides estimation bearings and ranges all buried objects as well error each observing array. Performances proposed investigated on experimental data recorded underwater experiments.
