Abstract :
High-resolution spatial spectrum estimation procedures in conjunction with narrowband multiple beam antenna (MBA) data are considered for source localization. The focus is on aspects of azimuth/elevation-spectrum estimation considering eigenspace estimators. Only two basic approaches to eigenspace spatial-spectrum estimators can be used with MBAs to provide unambiguous source azimuth/elevation estimates. These are the MUSIC approach and the recently developed first principal vectors (FINES) approach. Of these, FINES is recommended because it provides higher resolution
