Abstract

An array system, which provides a unipolar acoustic impulse with a broad spectral response underwater, utilizes a vertical array of air gun or electric spark sources whose individual peak source strengths are essentially constant over the array length, but whose individual source periods vary with depth. The array of sources produces in each instance a near-unipolar, impulsive signature with a broad pedestal-like spectrum. The system may be used for underwater object location and also for seismic exploration.
