| الوصف: | We present a modified version of Keto's (1992) array optimization program which finds antenna locations which most nearly produce a uniform Fourier plane coverage, subject to constraints on where the antennas can and cannot be placed. Rather than solving the abstract problem of determining a good shape for the array and then trying to fit the array shape onto a geometrically non-optimal site, we can instead seek the array shape which gives optimal Fourier plane coverage considering the details of the site. As an example, we show how a 12 km array fits onto the geometrically limiting Chajnantor site. Antenna plane constraints, such as are present for a 12 km array on the Chajnantor site, require long (u; v) tracks, rather than a single "snapshot", in order to obtain good Fourier plane coverage. The array configurations we obtain from optimizing the (u; v) coverage over 4 hour tracks, for either an unconstrained antenna geometry or the constrained Chajnantor site (which has a 4 km gap wh. |
