WebThe U.S. Air Force's over-the-horizon-backscatter (OTH-B) air defense radar system is by several criteria the largest radar system in the world. Six one-million-watt OTH radars see far beyond the range of conventional microwave radars by bouncing their 5-28-MHz waves off the ionosphere, an ionized layer about 200 km above the earth. WebN/A. Abstract. Over-the-Horizon radar (OTHR) uses ionospheric reflection to propagate HF transmissions to long range (~ 500 to 5000 km). The ionosphere is a dynamic “mirror” that varies diurnally, seasonally, and with the solar cycle. Geolocation of targets observed by OTHR, (Coordinate Registration; CR), requires accurate real-time ...
