Podsolnukh-E

The Podsolnukh-E, (Russian designator: 5P21, Kyrillic: 5П21 «Подсолнух-Э», “sunflower”) is operating in the HF-band (IEEE designation) or in the A-band (NATO designation) bistatic stationary over-the-horizon surface wave radar. The radar is used as a coastal surveillance radar and is designed for the all-weather detection of surface crafts and air targets by continuously monitoring the sea areas and the airspace in the Exclusive Economic Zone.

The radar can automatically detect, track and classify up to 300 sea and 100 air objects beyond the radio horizon, determine their coordinates and issue target designations to complexes and weapon systems of ships and air defense systems. Its distinguishing feature is a giant receiving antenna array up to 5 kilometers long and five meters high. The distance between the transmitter site and the receiver site is between 0.5 and 3.5 km. The radar covers a sector of up to 120°. The maximum power consumption is 200 kW.

The Podsolnukh radar system passed the Russian government tests in 2006. The letter E in the name Podsolnukh-E marks the export version.
