ticularly marine, data gathering system, the model incorporating factors that have been identified as significant contributions to amplitude, such as directivity, divergence, attenuation, interbed multiples, and transmissivity. The model is generated from the mathematical manipulation of well log data and data gathering system characteristics into a seismic range equation, namely: See Patent for Mathematical Equation where Er(f) = received energy density E(f)=radiated energy density D(I thetas, phis,0=source directivity along thetas, phis direction at the source Ac( thetaH, phiH,f)=Capture area along thetaH, phiH direction at the hydrophone array RT=target reflection coefficient Dv = divergence See Patent for Mathematical Equation One preferred use of the resulting modeled waveform is in a preprocess comparison with actual seismic data for validating and interpreting such actual data. Another use is in the deconvolution of seismic data for improved resolution.
A deep submergence, acoustically stable directional transducer uses a waveguide and an encapsulant to channel sound. The waveguide forms an air space with a housing so that radiated sound is totally reflected at the air space interface. The encapsulant is matched to the acoustic impedance ofthe sea water at the intended operating depth to minimize reflection at the encapsulant-to-sea water interface.

A marine acoustic array employs a plurality of sections connected together sequentially with the outer surfaces of said sections having a nonsmooth configuration to create a water flow along the length of the array as it is towed through a water layer that causes sensors within the array to provide outputs having improved signal-to-noise ratios.
