Prometheus Inc. has simulated, for the first time, real-time broadband torpedo
reverberation. The "noiselet" reverberation simulator compares extremely well
with the previous Weapons Analysis Facility (WAF, NUWC Newport) reverberation
generator with significantly fewer limitations and at lower cost. It
outperforms that WAF reverberation generator for the case of broadband
signals. Also, it is not limited to the case of Gaussian noise and does not
require any stationary assumptions. Our computations increase linearly with
the number of array elements whereas those of the previous method used in the
WAF increase with the cube of the number of elements. For these reasons, this
Prometheus reverberation simulator has been implemented in the WAF. This
allows the U.S. Navy to test its torpedoes in real-time at significantly
reduced cost. The Australian Navy is also enjoying these benefits, as the
Prometheus reverberation simulator is also in use in their WAF in Edinburgh
(Adelaide), Australia.
