"Real time" broadband adaptive matched field processing

Abstract

During the past year the CEROS program has funded a project to implement a broadband "real time" signal processing and propagation modeling suite at the Maui Supercomputing Center (MSC) that could be run via a Web-based user interface described by Gever and Fabozzi (see Oceans 2001 Conference, 2001). This processing suite takes advantage of the parallel computational resources at MSC, specifically the IBM SP2 multinode processor as well as PC clusters currently being brought on board or developed at MSC and SAIC. Our processing suites are a logical application of such machines because of the highly parallel nature of our codes which can typically be decomposed by frequency, space, or time. Our typical problem for which we demonstrated a "real time" throughput was for a 30 element array, a search volume of 90 degrees in bearing, 0 km to 10 km in range, and 0 to 100 meters in depth. This was done for a 100 Hz signal bandwidth.
