This paper describes and analyses a simple adaptive array based on the use of perturbation algorithms on a null steering beamformer proposed by Davies [1]. The convergence time constants and misadjustments of using these algorithms are derived. It is shown that, from choosing the feedback factors appropriately, the time constants can be roughly equalized, resulting in faster convergence behaviour.
