Characterization of a Phased Array Feed Model
<p>Creating accurate software based models of phased array feeds (PAFs) is one of many steps to successfully integrating PAFs with current and future radio telescopes, which is a goal of many groups around the globe. This thesis characterizes the latest models of a 19 element hexagonal PAF of …

Nineteen-Element Phased-Array Feed Development and Analysis on Effects of Focal Plane Offset and Beam Steering on Sensitivity
… platform to a nineteen-element platform for phased array feed experiments. The nineteen-element system was deployed at the National Radio Astronomy Observatory (NRAO) in Green Bank West Virginia for use on the Green Bank 20-Meter Telescope. Numerical simulations were performed to determine …

Beamforming Techniques and Interference Mitigation Using a Multiple Feed Array for Radio Astronomy
… frequency interference can be mitigated using a phased array feed in conjunction with a large reflector. A phased array feed would allow radio astronomers to observe fainter signals than is currently possible, while at the same time enabling rapid sky surveys. A phased array feed was designed and …

Single-band and Dual-band Beam Switching Systems and Offset-fed Beam Scanning Reflectarray
The reflectarray has been considered as a suitable candidate to replace the conventional parabolic reflectors because of its high-gain, low profile, and beam reconfiguration capability. Beam scanning capability and multi-band operation of the microstrip reflectarray have been main research topics …
