阿雷西博望远镜的宽视场接收器目前正在开发中，即阿雷西博高级L波段相控阵相机（ALPACA）。阿雷西博光学系统为相控阵馈源的优化设计提出了新的挑战。我们报告的结果，旨在确定元件的布局和几何形状，最大限度地提高接收器的灵敏度，视野和调查速度的模拟和设计优化研究。
A wide-field receiver for the Arecibo Telescope is currently in development, the Advanced L band Phased Array Camera for Arecibo (ALPACA). The Arecibo optical system provides a new challenge for design optimization of phased array feeds. We report on results from a simulation and design optimization study aimed at determining the element layout and geometry that maximizes the receiver sensitivity, field of view, and survey speed.
