In marine seismic work, various types of devices can be used as an energy source. One of the most popular is the air gun, which was designed to minimize damage to marine life. Typically, an array of air guns is used to produce the source wavelet. Such low-amplitude source signals generally are not minimum phase. Detailed knowledge of the signatures of air-gun arrays can be obtained by directly measuring their signatures. Such an approach can be expensive if it is implemented at every shot point. As a result, computer models often are used to estimate the signatures.
