Sepehr

Sepehr ( Persian سپهر'Sky') is Iran's over- the- horizon radar (OTH) . It is operated by the air forces of the Iranian Revolutionary Guard . The system went into operation in 2013. The exact location is secret. A similar system was established near Ahwaz .

Little is known about the facility in public. It is said to have a range of 2500 km and went into operation in 2013. The system should enable 3D images. Measurements showed that no FMCW modulation is used, but a wide, pulsating signal. The bandwidth of the occupied signal therefore varies extremely from 60 kHz to over 1 MHz. The signal is broadcast in the range around 28 MHz ( 10 m band ).

Individual sources claim that the system can detect American stealth bombers . Ballistic missiles that are fired at Iran should be able to be detected early with the system.
