Preliminary Designs for an Internet Based Antenna Array

Draft Design

The first steps to development of an array system are specification of science goals and technological feasibility study. A major motivation of the project is to allow independent student groups to use the individual telescope elements for science education goals. A science and engineering curriculum must be developed simultaneously.

A first draft science and technology document is available in PDF format.

The science goals of the Internet Antenna are similar to those for the proposed Low Frequency Array (LOFAR and LWA) projects. The proposed International Square Kilometer Array also has a distributed network of antennas, but will operate at higher frequencies. Rick Fisher, of NRAO Green Bank, is working on a number of related topics in beam forming and noise cancellation technology.

The development work of Gie Han Tan and Christof Rohner on "The Low Frequency Array active antenna system" is potentially very valuable for the Internet Array Element design ( postscript, pdf).
