An experimental study in forming a long synthetic aperture in the sea

Abstract

In sonar systems the requirement to increase the array gain and to achieve high bearing resolution becomes more important and more difficult to achieve, as the frequency is reduced t o increase the detection range. This requirement, however, of very long towed arrays to provide higher low frequency bearing resolution leads to serious technical and operational implications. As a result, many attempts have been made to increase the effective length of a conventional array by applying so-called 'synthetic aperture techniques'.
