The purpose of this research is to create a real-time, three-           dimensional ultrasonic imaging device that can be used by an underwater         robot.  It will employ techniques combining spread spectrum systems and         sparse arrays.  First, a device will be constructed to measure the              coherence time for the underwater channel and for use as a general              purpose imaging system.  Then, the results of the coherence measurements        will be incorporated into the design of the spread spectrum signals.            The result of the signal design will be tested via computer simulation          and physical measurement.  Subsequent investigations will include               refinements on signal coding, spatial coding techniques, and the                performance limitations inherent in such an ultrasonic device.  A               successful development under this grant will help to advance the state          of the art of vision sensors useful for robots in vision-impaired               environments, particularly underwater.
