Null steering in linear arrays by using amplitude control of signals in the feeder network
Abstract
A method of steering nulls in linear arrays by using amplitude control, rather than phase shifters, is described. The system is extended to steer all of the independent nulls in an array of any size. The problem of grating nulls is briefly discussed, and it is shown how an automatic null-steering array can be designed.
