A low-frequency hyperbolic frequency modulated signal (HFM) was employed to measure propagation loss in both a deep water environment and in a shallow water surface duct environment. The shallow water measurements indicated that loss of signal coherence increases the propagation loss measured, in this case by 5 dB to 10 dB over this range. ER -
