Sensitivity of the high-resolution eigenanalysis methods to estimated number of sources

Abstract

INTRODUCTION One of the primary purposes of radar sensor arrays is the determination of hearings of clmely spaced radiating sources. DiEiculties arise when, in addition to direct paths there exist multipath components in the received signal. Multipath components are scaled and delayed replica of the direct signal, propagating a t the same frequency and are fully correlated with the direct received signals.
