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 ID phased array () and a second ID phased array (), where the first ID phased array sends a set of signals and receives a set of reflections based on the set of signals, and the second ID phased array receives the set of reflections.

Calibrating radars and tracking space objects

A method for orbital collision screening comprising, obtaining trajectory information of a plurality of objects moving on predictable paths. For each one of the plurality of objects, based upon respective trajectory information of the one of the plurality of objects, computing, a respective spatial descriptor of the path of the one of the plurality of objects, and storing the respective spatial descriptors of each of the plurality of objects in a data structure. Subsequently obtaining trajectory information of a further object, and based upon the trajectory information of the further object, computing a spatial descriptor of the path of the further object. Making first comparisons of the spatial descriptor of the further object against the respective spatial descriptors of each of the plurality of objects stored in the data structure to determine whether each of these first comparisons indicates a possible collision risk. Based upon each of the first comparisons, if the first comparison indicates a possible collision risk, determining a result of a close approach determination between the respective trajectory information of the respective one of the plurality of objects and the trajectory information of the further object, and taking an action based on result of the close approach determination satisfying a predetermined threshold.

System and method for orbital collision screening

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.
