摘要：
Using classical array theory this paper presents directivity, sidelobe, and bandwidth performance analysis over narrow and wide bandwidths in the microwave frequency region for several large cylindrical array configurations comprised of panel subarrays. The degree of main beam spreading, grating lobe levels, and directivity loss is presented for several designs involving trade-offs between true time delay beam scanning and phase shifter beam scanning. It is also shown that the grating lobes may be reduced with an amplitude taper across the array.
