WebUltrasparse, ultrawideband arrays. Abstract: This paper investigates the properties of … WebNB radiation patterns (a, b, c) and UWB maximum projections (d, e, f) of three 18λ linear arrays. (a, d) 37-elements, λ/2-spacing; (b, e) 10-elements, periodically thinned, 2λ spacing; (c, f) 10-elements, randomly thinned arrays, 2λ average spacing. u = sin θ is the reduced azimuth angle, θ = angle from array normal.

Web26 Jul 1996 · Ultrasparse, ultrawideband phased arrays. Abstract: Current technology in … WebThe equivalent arrays in (a) and (b) have element shadowing. Their maximum projections have higher SL than (c) and (d), which have no shadowing. The equivalent array in (d) has the lowest SL because it has no element shadowing and a periodic arrangement of elements.
