ABSTRACT:
The invention relates to hull sonars for a naval vessel. The hull sonar includes associating a transmitter formed by cylindrical rings with a receiver formed by at least two sets of hydrophones distributed over two transparent cylindrical surfaces that are coaxial with the transmitter. Thus, it is possible to reduce the weight and the total volume of the antenna and to compensate for the effect of the quality factor Q.
