Abstract

The problem of optimizing the (u, v)-plane coverage of a rotating phased array of telescopes is assessed. We search for solutions for maximum uniform (u, v)-plane coverage. Using a simulated annealing algorithm, we find the optimal configurations for rotating arrays with between four and 10 identical telescopes. With few modifications, the same algorithm can find optimal array configurations adapted to specific observations for which the optimal (u, v)-plane coverage is different. We also demonstrate that such rotation-optimized arrays are capable of recovering images of complex sources and obtaining spectroscopic information.
