Abstract
Frontal sonar for observing the seafloor, characterized in that it includes: elements for insonifying a seafloor area divided into M sectors, able to perform a characteristic insonification of each sector of the area during an operation recurrence of the sonar; and receiving elements including a physical antenna consisting of an array of K transducers, the antenna being lacunar and thus ambiguous, so that it defines N image lobes, and in that each of the characteristically insonified sector is associated with a single image lobe defined by the antenna, so that the antenna ambiguity is removed.
