Talk Title
Spectrum and RFI Sensing using Digital Multi-Beam Circular Apertures
Description of Talk
Radio spectrum monitoring across 360-degree field-of-view (FoV) is a fundamental requirement for RF situational awareness. RF awareness demands sensed intelligence on the direction of arrival, frequency occupancy, modulation type signal power, and bandwidth for each waveform present. This article includes an end-to-end design and realization of an array processor, consisting of sixteen uniformly spaced antennas in a circular array at 2.4 GHz, providing 360-degrees FoV using digital multi-beam beamforming.
