Abstract
Propagator Method (PM) algorithm is a common method for the estimation of direction of arrival (DOA). In this paper, we propose a reduced dimension PM (RD-PM) algorithm for non-circular signal with linear array. We reduce the dimension of the pseudo spectrum function so that we need only one dimensional searching, which decreases the computational complexity. And the exploiting of the noncircular property improves the accuracy of estimation. Extensive simulations illustrate the effectiveness and improvement of our algorithm.
