Effect of digital phase shifters on phase only controlled SLS difference patterns

Different beam shapes are produced from array antennas with well designed additional phase distributions. This is digitized and introduced to the array elements with the use of digital phase shifters in fast scanning and beam changing applications. However, these phase shifters introduce quantization errors on the radiation patterns. Such errors/effects on sidelobe suppressed (SLS) difference patterns generated using the phase only control method are not available in the open literature. In view of this, the effect of digital phase shifters on the above type of patterns is shown
