Non‐uniform array synthesis concept and theory.

Uniform or symmetric array is a common practice for most of the sonar array design, where the same performance transducer elements are used for numerical simulation and manufacture engineering conveniences. However, non‐uniform array designs show their advantages for special array applications. This paper will theoretically address the non‐uniform array synthesis concept and theory. A few numerical examples will also be presented for element hybrid and cluster special arrays. [The work is supported by the U.S. Navy.
