The Distortion of a Sonar Pulse Reflected from the Ocean Surface.
Abstract
Equations are derived for the direct evaluation of a sonar pulse reflected from a time-varying ocean surface. Fewer assumptions and approximations are made in this direct approach than in conventional developments of scattering theory. However, the cost of computer time may become excessive for some cases. The calculated surface reflected signals are correlated with the incident sonar pulse to find the expected correlation loss of a sonar processor. For a short (5 msec) low frequency FM slide the calculated correlation losses (1.6 dB for the surface generated by a 10 knot wind and 3.9 dB for a 20 knot wind) were almost entirely the result of energy loss in the reflected signal.
