Abstract
An improved sonar system of the type wherein a plurality of acoustical beams are transmitted with directional characteristics which are simultaneously swept over adjacent sectors of the observation area. The transmitting directional characteristics of each pair of adjacent sectors are swept or pivoted over their respectively associated sectors in a continuous manner and in opposite directions so that they leave and reach the common borderline between the sectors at the same instant of time.
Claims7
In a sonar system having a transmitting arrangement for the simultaneous sweeping of a plurality of transmitting directional characteristics in respective adjacent sectors of an observation area, the improvement comprising:
- means for causing the transmitting directional characteristics in each pair of adjacent sectors to sweep over their respective sectors in a continuous manner and in opposite directions so that the respective transmitting directional characteristics leave and reach the common borderline of the sectors at the same time.
In a method of transmitting sonar energy wherein the transmitting directional characteristics of a plurality of bundled beams of acoustical energy are simultaneously pivoted over respective adjacent sectors of an observation area, the improvement comprising:
- pivoting the transmitting directional characteristics in each pair of adjacent sectors in a continuous manner and in opposite directions so that the respective transmitting directional characteristics leave and reach the common borderline of the sectors at the same time.
