High-speed simulation of an underwater acoustic field using an array processor
A computer model PAREQ for simulating the acoustic field of sound propagating in a complicated ocean environment has been installed on a realtime computer system (HP MX21) which includes an array processor (MAP 300). The use of the array processor has resulted in a reduction in running time of a factor of one hundred over previous usage on a general-purpose computer (UNIVAC 1106). Consequently, parametric studies, which prior to this installation were impractical to perform, can now be made. The model can be used for at-sea interpretation of experimental results and for the simulation of data which would be received by various acoustic arrays and analyzed by this same real-time computer system. Hence, array configurations and signal processing schemes can, to some extent, be tested before the actual sea trials.
