Lateral beam projections of the singular window functions and dual-/tri-apodization. Lateral beam projections of (a) rectangular window function (R.W), Dolph-Chebyshev window function (D-C.W), and Kaiser window function (K.W), and (b) rectangular window function (R.W), dual-apodization (D.A) using rectangular and Dolph-Chebyshev window functions, and tri-apodization (T.A) using rectangular, Dolph-Chebyshev, and Kaiser window functions at the focal point. Note that the rectangular window function was used for reference window to compare the performance of several window functions and D.A/T.A.
