In convex arrays, the beams transmitted are designed to be:

• A. Parallel
• B. Not parallel
• C. Converging
• D. Diverging

Answer: (B)

A convex array uses a curved aperture, so the transmitted wavefront is curved rather than flat. When the elements fire with the right timing, the resulting beam fans out as it propagates, causing the individual beam directions to diverge from one another. This non-parallel, spreading pattern is intentional to cover a wider area and provide a larger field of view. In short, the beams are designed to be not parallel because the curved geometry inherently makes the transmitted wavefront non-planar and these rays spread as they travel.
