Abstract:

A Wide Swath Precision Echo Sounder is provided by means of transmitting programmed acoustic pulses pings to insonify a target area and receiving the backscattered energy in two receivers separated vertically. The outputs of each receiver are stored including phase information and synthetic aperture outputs are generated. Each space resolution cell will have a phase associated with it for each receiver. Using the interferometer technique, the phase is converted into a depression angle and is combined with the slant range to the particular space cell to provide a numerical measure of the depth and lateral range to the particular spot under consideration.
