Reduction in peak side lobe level (PSLL) in addition to null placement for antenna array can be achieved by optimizing the amplitude weights of the feeding current. The optimized weights are obtained through Genetic Algorithm solved with multiple linear constrains to achieve desired response. The algorithm is also shown to work for conformal antenna array with variable inter element spacing where...
Beamformer is an indispensible part of any phased array system. Analog beamformer is the simpler method where the individual signals received from array of antennas are co-phased and summed to maximize the signal reception. The co-phasing is achieved through data independent weights which are predefined as per direction of arrival. These weights are applied to the analog phase shifter IC, which produces...
