Impulse response of the ocean floor nonlinear techniques for measurement enhancement.

Describes a procedure for enhancement of impulse response measurements of the ocean floor. When these measurements are made with explosive charges the source waveshape obscures much of the detail in the received signal. The effects of this source waveform can be eliminated by various forms of deconvolution. Homorphic deconvolution is very flexible in its application and does not require foreknowledge of the source waveshape. The special problems such as phase reconstruction and signal conditioning are discussed in the context of ocean floor measurements with explosives, and a computer code is presented that generates and checks the log-spectrum. -from STAR, 21(20), 1983
