Over-the-horizon radar |
|
|
Over-the-horizon radarOver-The-Horizon radar (OTHR) is a design concept for radar system to overcome the problem that radio waves propagate along a linear axis and thus in practice cannot detect reflections below the horizon. A 1998 publication by the Australian Department of Defence contemplated bouncing radio waves off the ionosphere in order to detect images below the horizon. External links
