Suboptimal frequency domain adaptive array processing in a broadband environment

This paper concerns array processing in a broadband environment. A frequency domain algorithm is proposed in which the complex weight vector W
k
(k) for each FFT cell is a function of cell number k. Using prespecified frequency bands the S/N ratio of the output is optimised with respect to the undetermined variables in W
k
(k). The algorithm is robust and requires far less work load than frequency domain techniques. The system is capable of steering several -50dbs broadband nulls.
