We are developing a 2 to 25 MHz antenna array for radar and radio imaging of the ionosphere. The main array will be located near Arecibo in Puerto Rico, and will include 64 active crossed antenna elements within a 400-meter-diameter area. Relocatable antenna elements will also be included, with phase maintained through the use of GPS-disciplined rubidium clocks.
