tapped delay line filters

|Abstract:||In this paper, the nulling performance of a 2-element broadband linearly constrained array employing tapped delay line processing is investigated by using a first order small bandwidth analysis as well as by using computer simulation. It is shown that even-tap arrays have better nulling performance than odd-tap arrays, and for even-tap arrays, the average null depth is given approximately by (fractional bandwidth/2)number of taps. The results obtained can be used to determine the important design parameters in broadband arrays implemented using either tapped delay line processing or several narrowband real-and-quadrature arrays in parallel. Specifically, it is found that the former broadband processing method requires considerable less adjustable weights than the latter one. © 1989.|
