Title: | Nulling performance of a broadband linearly constrained array | Authors: | Ko, C.C. | Keywords: | Array processing tapped delay line filters |
Issue Date: | Aug-1989 | Citation: | Ko, C.C. (1989-08). Nulling performance of a broadband linearly constrained array. Signal Processing 17 (4) : 313-320. ScholarBank@NUS Repository. | 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. | Source Title: | Signal Processing | URI: | http://scholarbank.nus.edu.sg/handle/10635/80843 | ISSN: | 01651684 |
