Abstract
A computer system for angle of arrival estimation receives one or more snapshots from a circular array of antennas. The computer system processes the one or more snapshots for amplitude and/or phase-based direction finding using two cascaded algorithms. The first algorithm of the two cascaded algorithms is configured to identify a target subregion from which a signal arrives. The second algorithm of the two cascaded algorithms is configured to identify a direction of the signal within the target subregion.

A computer system for angle of arrival estimation comprising:
- one or more processors;
- and
- one or more computer-readable media having stored thereon executable instructions that when executed by the one or more processors configure the computer system to:
- receive one or more snapshots from a circular array of antennas;
- and
- process the one or more snapshots for amplitude and/or phase-based direction finding using two cascaded algorithms, wherein:
- a first algorithm of the two cascaded algorithms is configured to identify a target subregion from which a signal arrives, and
- a second algorithm of the two cascaded algorithms is configured to identify a direction of the signal within the target subregion.
A computer-implemented method, executed on one or more processors, for angle of arrival estimation, the computer-implemented method comprising:
- receiving one or more snapshots from a circular array of antennas;
- and
- processing the one or more snapshots for amplitude and/or phase-based direction finding using two cascaded algorithms, wherein:
- a first algorithm of the two cascaded algorithms is configured to identify a target subregion from which a signal arrives, and
