An expandable sonar array structure (10) includes a central body (12) with a plurality of radially extendable hydrophone support arm assemblies (16) attached to said body and including a motor-driven drive member (20) to which all the arm assemblies are attached through pushrods (38, 40). Each arm assembly (16) includes three substantially vertically aligned, radially extending arms (22, 24, 26) carrying hydrophones (42) with top and bottom arms attached to the pushrods (38, 40) through short arms with pivots chosen so that the arms move in opposite directions. |
