A Novel Small Aperture Direction Finding System Based on Phase Mode Antenna

2024 IEEE International Symposium on Antennas and Propagation and INC/USNC‐URSI Radio Science Meeting (AP-S/INC-USNC-URSI)
A novel small aperture direction finding (DF) system based on phase mode antenna (PMA) is proposed to estimate the angle of arrival of (Ao $A$) signal without ambiguity.

DSSS detection and direction finding methods for a DSP-based small aperture DF system

2014
This dissertation discusses an investigation into methods for detection and direction finding of direct-sequence spread-spectrum signals (DSSS), appropriate for a particular DSP-based direction finding platform. Relevant details on DSSS and radio direction finding are presented. These are used as the theorectical basis for the developemtn of a software-
