Abstract
Correlation interferometry direction finding (CIDF) processes that significantly improve processing time and cut memory requirements relative to the current memory requirements are provided herein. The presently disclosed processes further may utilize only the real portion of the correlation coefficient of the RF signal to further increase processing speed and decrease memory requirements while simultaneously improving direction finding accuracy and reducing the number of wild bearings reported.
