| Abstract: |
Aperture synthesis radio telescopes generate images of celestial bodies from data obtained from several radio antennas. Placement of these antennas has always been a source of interesting problems. Often, several potentially contradictory objectives like good image quality and low infra-structural cost have to be satisfied simultaneously.
In this paper, we propose a general Minimum Variance method that focuses on obtaining good images in the presence of limiting situations. We show its versatility and goodness in three different situations: (a) placing the antennas on the ground to get a target Gaussian UV distribution (b) staggering the construction of a telescope in the event of staggered budgets and (c) whenever available, using the mobility of antennas to obtain a high degree of fault tolerance. |
