Effect of Update Randomization on REVGEN Output: Matched Filter Processor.
Abstract
Rapid advancements in undersea weapon technology and signal processing have required improvements in accurate simulation of ocean reverberation. A NOSC effort in this area has included the implementation of REVGEN (A REVERberation generation program developed by the Applied Physics Laboratory at the University of Washington). However, the requirement that this simulation operate in real time has required several simplifying modifications to the original REVGEN concept. This report examines the effect of various REVGEN algorithms on the output of a matched filter processor and, by analyzing the amplitude distribution of the range-Doppler map, evalutes the resulting false alarm and detection statistics for the response of a two-dimensional variable threshold detector. Further, where changes in performance are significant, an alternate REVGEN algorithm is presented which is compatible with real-time operation on the NOSC Hybrid Simulator and, in some instances, actually reduces the computational requirements.
