Submarine Target Strength Estimates At 1 Khz

Abstract

The 1 KHz monostatic and bistatic target strength for an attack class nuclear submarine is calculated based upon the extrapolation of a regression model, developed previously, from data on the .233 scale model submarine, KAMLOOPS. These calculations were made to support the active detection performance evaluation of Naval Undersea Center's Expendable Sound Source surveillance system concept. The mean 1 khz monostatic target strength averaged over all aspects is 19.7 dB with a 24.9dB and 12.5dB beam and bow/stern aspect target strength, respectively. The 24.9dB beam aspect monostatic target strength agrees exceedingly well with a set of independent measurements made on KAMLOOPS. An expression for the calculation of the bistatic target strength is given.
