Abstract :
A solid-state phased array technique is introduced where some of the T/R modules each feed a single radiator while other T/R modules each feed multiple radiators. This technique provides higher ERP and gain along with narrower beams than the conventional T/R module per radiator approach for a given number of T/R modules. At the same time the amplitude quantization lobes, associated with an array of subarrays, are greatly reduced
