Abstract : Little experimental data exists which can be applied to the design and performance evaluation of multidimensional array systems. Such data are needed both to validate signal and noise propagation models as well as to provide well-documented real data inputs to new adaptive spatial and temporal processing algorithms. In preparation for a FY94 VLF noise and signal experiment, preliminary analysis of an existing near-seafloor data set was carried out, planning and preparation for a September 1993 engineering sea test were completed, and robust adaptive algorithms were developed for the processing of array data.
