Embodiments of a system and method for a forward looking sonar, for example, configured for use in an underwater vehicle, are disclosed. One embodiment includes a method of imaging a region. The method includes transmitting at least one acoustic pulse from a transducer and receiving a portion of the pulse scattered from a region. The method further includes generating a multi-channel signal based on the received portion of the pulse scattered from the region, sampling the scattering signal to generate a plurality of complex samples, and forming a plurality of beams in a horizontal plane based on the complex samples. The plurality of complex samples may be processed to obtain image data comprising angles of arrival from scattering components in a vertical plane for each horizontal beam. An image may be generated based on the image data. Other embodiments may include apparatuses such as sonar systems. |
