Reverberation Noise and Signal Generation Algorithm (RENSGEN)

Abstract

The purpose of this study was to develop an Artificial Intelligence Expert System to detect signals in a range-Doppler map of noise and reverberation. This memorandum documents the initial phase of the study, i.e., development of a mathematical representation for a gain-controlled range-Doppler map capable of simulating various in-water acoustic background conditions. The range-Doppler map representation was generated by an algorithm written in COMMON LISP identified as RENSGEN. RENSGEN was designed to generate a range-Doppler map with options for the presence of signals, noise, and a representation of reverberation assuming a pulsed pure tone transmitted signal. A simulated range-Doppler map of noise and reverberation generated by RENSGEN is shown in Figure 1. This work was the result of a joint effort by The Applied Research Laboratory and the Mathematics Department of The Pennsylvania State University. Through a Mathematics Work-Study program, they provide a one year assistantship to University seniors majoring in Mathematics.
