Radio Astronomy Systems
Dr. Brian Jeffs
The Radio Astronomy Systems group builds advanced radio camera imaging systems based on phased array technology for radio telescopes. The Focal L band Array for the Green Bank Telescope (FLAG) is currently operational at the Green Bank Observatory, a national astronomical facility in West Virginia. We are building the Advanced Cryogenic L-Band Phased Array Camera for Arecibo (ALPACA) for the Arecibo Observatory in Puerto Rico. The group uses electromagnetic theory, digital signal processing, microwave and RF circuit design, and computer engineering to develop systems that include antennas, signal handling electronics, and software running on FPGAs, GPUs, and CPUs for digital image formation.
