Abstract

The problem of resolving constant-amplitude narrowband signals with an M sensor uniform linear array is investigated. Recent work has shown that proper use of the constant-amplitude constraint allows the parameters of as many as 2M-1 signals to be estimated. Even though algorithms for estimating these parameters have thus far required excessive computation, little research effort has been devoted to reducing the computation. A new algorithm is proposed that is promising because of its computational efficiency and speed. Examples are presented to illustrate this algorithm´s performance
