Abstract
The disclosure relates to an imaging sonar for detection of objects buried in a reflecting medium, comprising a “vertical” transmit antenna and a horizontal receive antenna forming a “Mills Cross”, said transmission means enabling a vertical radiation angle producing a slightly ensonified area thereby reducing masking of the echo from said buried objects by acoustic backscatter from said reflecting medium. The invention is applicable to sonars and “sonar towfish” used for seafloor imaging and enables detection of sub-bottom objects buried in submarine sediments.
