“…To solve it, some solutions are obtained through a semidefinite relaxation of the constraint to transform the optimization problem into a convex problem that can be solved by means of well-known numerical tools [ (Gershman et al, 2010;Tranter et al, 2016;Tranter et al, 2017;Rixon Fuchs et al, 2022), and references therein]. Other existing strategies exploit statistical and evolutionary methods to find solutions as close as possible to the optimal one (Hatam, 2022). Suitable combinations of the aforementioned approaches can also be found in (Hatam, 2022).…”

In this letter, we address the problem of phase-only transmit beamforming to generate a wide beam with an almost flat mainlobe for phased arrays. Instead of resorting to time-demanding optimization procedures, the proposed method is grounded on the Fourier analysis and exploits the fact that radiation pattern can be written as the Fourier transform of the aperture illumination function. In this context, we consider a complex linear frequency modulated illumination function and derive the equations allowing for a control of the beam width. The related computational complexity is linear in the number of the array elements. The numerical examples show the effectiveness of the proposed method in forcing the desired beam shape with good sidelobes’ properties and also in comparison with an iterative competitor.
