How are space-tapered antenna arrays designed using deterministic methods?

I am studying array antennas and want to reduce sidelobe levels without sacrificing gain.
Deterministic tapering of element spacing is frequently mentioned, but I need a practical design methodology.
I want to know how to select element positions and excitations systematically.

From my experience, designing space-tapered antenna arrays deterministically involves systematically adjusting element positions and amplitudes to control sidelobe levels while preserving main beam characteristics. I have seen designers start with uniform spacing and apply tapering functions—such as Taylor or Chebyshev distributions—to element positions or excitation amplitudes. I would recommend using analytical equations to compute each element’s contribution, followed by EM simulation to validate performance. In practice, deterministic methods allow predictable pattern shaping, reduced sidelobes, and efficient beam control, making them preferable when computationally efficient designs are needed.
