Grating Lobe Characteristics of Arrays with Uniformly Illuminated Contiguous Subarrays,

reportActive / Technical Report | Accession Number: ADA142332 | Open PDF

Abstract:

This report presents simple approximate formulas and generalized curves to simplify evaluation of the grating lobe levels of various kinds of contiguous subarrays with uniform illumination within each subarray. The cases considered include phase quantization caused by discrete phase shifters, amplitude taper at subarray input ports, and time delay at the subarray input ports. Also, the work is generalized to include certain cases of quantized phase or time delay at the input ports in addition to amplitude taper at subarray input ports. Author
