Real-Valued Two-Dimensional Propagator Method Using Cross-Correlation Matrix

LI Lei;LI Guo-lin;Unit 91872of PLA;Department 7of Naval Aeronautical Engineering Institute;  
In order to improve the accuracy of direction of arrival(DOA)estimation and decrease calculation capacity with low SNR,a new real-valued propagator method(PM)for 2-D DOA estimation algorithm using cross-correlation matrix(UC-PM)was proposed.Instead of array received data,cross-correlation matrix was constructed to suppress the effect of noise,and eigendecomposition was replaced by a linear operator with low calculation capacity.Meanwhile,for reducing the complexity further,a new real-valued rotational invariance matrix was constructed to change eigen-decomposition and total least problems into real ones by unitary transformation.The simulation results showed that,being similar performance with 2-D ESPRIT algorithm,the performance of UC-PM is better than conventional PM algorithm with low SNR,and it has much lower calculation capacity than 2-D ESPRIT algorithm,which made the proposed algorithm of high practical value.
