Abstract
A method and apparatus for imaging underwater targets utilizing sidelookingonar. A sonar pulse consisting of a concatenated series of subpulses is transmitted. The echo return is match filtered against each of the subpulses to produce a series of range-doppler maps, each providing information in a different direction. The range-doppler maps are normalized, thresholded, and intersected, thereby yielding data points which describe the target outline. Information as to the target length, width and orientation can be computed from the target outline data.
