Abstract:
Technologies for calibrating radars and tracking space objects. Some of such technologies enable a technique for calibrating a radar based on using -A- an elemental antenna (), which can be embedded on a housing hosting a set of antenna elements, or -B- an antenna () mounted to a reflector. Some of such technologies enable a radar site containing a first 1D phased array () and a second 1D phased array (), where the first 1D phased array sends a set of signals and receives a set of reflections based on the set of signals, and the second 1D phased array receives the set of reflections.
