In this paper, an algorithm based on Ants Colony Optimization (ACO) is
proposed for extraction of the Directions of Arrival (DOA) of several signals
impinging on uniform linear arrays. This algorithm is used to reduce the
computation time and complexity that occur in Estimation of Signal Parameters
via Rotational Invariance Technique (ESPRIT). In order to illustrate the accuracy
and flexibility of the proposed algorithm, several simulation cases introduce of
ESPRIT-DOA estimation by using ACO algorithm in environment of Matlab 7.8
program. Results are statistically analyzed in order to conclude from it the
algorithm's accuracy and reliability
