A Modified ESPRIT Algorithm for Direction Finding
Zhou Qing-hui · Radar Science and Technology · 2005
To know the source number is needed when using ESPRIT algorithm for direction finding.In this paper,ESPRIT algorithm is modified.In the modified algorithm,source number estimation and direction estimation are combined efficiently.The algorithm needs less computational work without impairing the performance of direction finding.The computer simulation is performed.The simulation results show that the modified algorithm is feasible and effective.
