Abstract:
A method of compensating for atmospheric effects while using near horizon radar to detect an object, said method utilizing a preexisting satellite wherein the location of the satellite is known, said method comprising the steps of:a) providing a radar site, a first receiver structured to receive a signal from said satellite, and known location data for said satellite; b) positioning said first receiver near said radar site; c) utilizing said first receiver to receive a signal from said satellite when said satellite is at a low elevation, said signal indicating the apparent location data of said satellite; d) determining the bending angle of the atmosphere by comparing the apparent location data of said satellite as determined by said first receiver to the known location data of the satellite; e) using the radar site to detect the apparent location data of a low elevation object; and f) determining the location of the low elevation object by applying the bending angle to the apparent location data of the object.
