Sample text

At the upper range of SLR the main-lobe power almost reaches to saturation; thus ATE is mostly decided by the beam width. 25 Dolph–Chebyshev arrays showing that larger SLR corresponds to a wider beam. 26 Array taper efficiency versus SLR for two D–C arrays. with SLR, the ATE decreases. Furthermore, the power in the side lobes is smaller for a smaller N than that with a larger N . Therefore in the case of a smaller array, the main-beam power controls ATE only within a limited range of SLR, implying that the ATE peaks at a smaller SLR.

2 Scan Array Design Consideration The scan loss has a very important role in designing a scan beam array. 8 Plot of array factors for different scan angles in the sin space. 0 15 PENCIL BEAM ARRAY gain of 40 dBi. 4 To aid the design trade, we must understand the relation between the array aperture size and the total number of elements that would satisfy the gain requirement. Toward that pursuit we first consider a uniform excitation. The effects of the amplitude taper will be considered later. 38) √ because Bn = 1/ N for all n.

30) For a uniform taper, the ATE is 100%. For a nonuniform taper it is less than 100%. The array aperture efficiency is the product of the ATE and the element aperture efficiency in the array environment. Thus, the ATE has a very important role in deciding the overall aperture efficiency of the full array. 4. 3 PENCIL BEAM ARRAY A pencil beam array is generally referred to as an array that produces narrow beams. Thus, a pencil beam array exhibits maximum possible gain in a desired direction. Typically, the amplitude taper of such an array is decided by the sidelobe requirement; thus only the element phase is adjusted to maximize the array gain.
