WebBeamforming properties of linear PWAS array have been investigated. It was found that several parameters can be used to manipulate the array beamforming. They are: ratio d/λ, ratio r/d, number of elements M, steering angle ϕ 0, and weighting factors w m. The main conclusions are: • Larger d/λ results in thinner mainlobe width.
