Performance analysis of broadband concentric circular antenna array processor

The broadband concentric circular antenna array beamformer with convolution constraints and efficient realization techniques are addressed in this paper. The concentric circular array processor is competent to scan a beam azimuthally through 360 degree and inherently cover up the entire breathing space. The behavior of the time domain element space array processor is appraised by comparing its recital, sensitivity to the stare direction and computational effectiveness. The simulation effect shows that the proposed processor has superior performance than the existing circular processor. It has capability to steer the main beam at any random direction without using presteering delays and has aptitude to cancel directional interferences as well.
