The success of examining the bandwidth performance of a wideband antenna array relies on the optimal performance of each element present to signal processing. This is examined in terms of the direction of arrival (DOA) i.e. the direction of the interfering signals (desired signal and desired interference signals) and the interspacing between the tapped delay and length of the taps with the weights. The performance of the bandwidth is examined for a two element adaptive array with the use of the tapped delay line technique by keeping each element behind the tapped delay line. When a tapped delay line is introduced, the signal to noise-interference ratio improves for various signal bandwidths resulting in an increase of sensor numbers in the structure of the narrowband beam former and by varying the length of the tapped delay lines (TDL’s) to obtain a well known wideband beamforming structure. These TDL’s along with traditional linear array combine well to form an effective and well known beam form. “The characteristics are in such a way that they form a beam effectively with its azimuth range of over half and its...
