dc.description.abstract | An issue of concern for matched-field processing is the strong dependence between performance and | |
dc.description.abstract | precise knowledge about the environmental parameters. Recently a robust matched-field processor | |
dc.description.abstract | based on minimax robust filtering methods was developed. In this report simulation methods are | |
dc.description.abstract | employed to evaluate the performance of the minimax robust method as well as other robust methods | |
dc.description.abstract | for a range-independent shallow-water environment. The performance of the robust methods is | |
dc.description.abstract | compared with that of the nominal processor, that is, the processor based on a single set of environmental parameters thought to be closest to the actual. The matched-field processing performance is evaluated in terms of the peak-to-sidelobe ratio, the simulation results indicate that the robust methods provide significant performance improvements over the nominal processor in the presence of uncertainty in water-column sound-speed, channel depth and sound speed in the bottom. | |
