Data Selection for Fast Projection Techniques: A Comparative Study of Direction Finding Performance

Abstract

This report describes simulation studies of fast projection techniques for direction finding of jammer signals. These techniques are based on a data selection criterion applied directly to the data vectors obtained at the output of an antenna array. The selected data vectors are used in fast projection algorithms to estimate the jammer subspace and then calculate the directional spectrum. Three such algorithms are described ranging from the fastest but least effective to the most computationally demanding but most effective. These algorithms provide a better tradeoff of performance versus computational load than has heretofore been available. Relative performance is compared with that of the MUSIC technique for test cases which evaluate the minimum resolution threshold achievable and the effect of the jammer strength relative to the receiver noise.
