Abstract

In this project, we are trying to detect the direction of arrival of incoming radiation in the far-field region. To achieve this, we implemented a very flexible and low cost wideband 8x1 phased array antenna receiver system that performs digital beamforming. We designed and built ten aperture coupled patch antennas, radio-frequency (RF) front ends and intermediate-frequency (IF) stage blocks for each channel. Finally, we stored the data in the first-in-first-out (FIFO) memory placed on a Vertex6 FPGA on which we synthesized a microblaze microcontroller that uses SPI to control programmable RF devices and transfers data to the computer for further processing. Super-resolution direction of arrival and model order detection algorithms were implemented to perform the digital beamforming.
