Description[edit]

Used by militaries for very long range radar systems. Some systems are transmitted by burst, where others are more persistent. The Russian 29B6 'Kontayner' OTHOver The Horizon (very long range) Radar and UK's Cyprus-based PLUTO II OTHOver The Horizon (very long range) Radar both exhibit persistent behavior. OTHOver The Horizon (very long range)'s can hop frequencies in a erratic manner, even hopping into broadcast and amateur radio bands.

OTHOver The Horizon (very long range) Radars have varying bandwidths and sweeps/sec. The most common sweep frequencies seen are 25 and 50 sweeps/sec.

Samples[edit]

25 Sweeps/Sec

40 Sweeps/Sec

50 Sweeps/Sec


Various Samples:

@ 20 MHzMegaHertz (MHz) 10^6 Hz.

Frequencies[edit]

All over the HFHigh Frequency (3-30 MHz) band.
