In 1997 Papazoglou and Krolik [11] devised a technique for using matched field processing to measure the altitude of aircraft targets being tracked by an OTHR using a single coherent dwell of radar data.

The Proposed Action includes acquisition of land, construction, and operation of two Homeland Defense Over-the-Horizon Radar (HLD OTHR) systems in the Northwest region of the United States.

Over-the-Horizon Radar (OTHR) is a very long range radar system that uses the ionosphere to bounce signals to detect incoming threats.
