Abstract : Parametric sonar has proven to be an effective concept in sonar applications requiring only a single transmitted beam and relatively low information rates. To be a viable candidate for the broad class of sonar applications that require search sectors greater than the angular extent of the parametrically transmitted beam, techniques must be developed to form multiple transmitted beams or an angularly scanned beam for the parametric source sonar. One technique has been evaluated and the report summarizes the results.
