Extended Array Evaluation Program. Special Report No. 3. Array Processing of Alaskan Long-Period Array Data

Abstract

The effectiveness of various array processors for the extraction of long-period Array data has been investigated. The types of processors discussed include frequency-domain and time-domain optimal multi-channel filters, adaptive filters, beamsteer and weighted beamsteer. It has been concluded that conventional multi-channel filter processors do not provide results superior to simple beamsteer processors when applied to ALPA data. There is some suggestion that on occasion adaptive multi-channel filters or weighted beamsteer processors have some advantage over beamsteer processors.
