Abstract
Antenna systems and methods of detecting RF signals received from a field of view (FOV) are presented, employing intersecting fan beam pluralities formed by associated columns or rows of antenna elements and cross-correlation of components of the received radiation from the fan beam pluralities. The intersecting fan beams pluralities form pencil-like beams persistently spanning the FOV as desired. Angle(s) of arrival and frequency channels of incident RF signals may be determined through power estimation, ranking and filtering, and/or frequency channelization techniques. Higher sensitivity beams may be cued to more accurately characterize the incident signals.
