Russia designs over-the-horizon Podsolnukh radar – take 2

MOSCOW, July 1. /TASS-DEFENSE/. Podsolnukh radar demonstrated its capabilities at Vostok-2010 exercise. Several dozen warships of three fleets gathered at the final stage of the maneuvers in the Pacific theater of warfare. The Northern and the Black Sea fleets sent their biggest warships to the Far East - the Petr Veliky cruiser of project 11442 and the Moskva cruiser of project 1164.

The navy force trained fighting submarines and warships, interacted with aviation, repelled a hostile amphibious assault and ensured the landing of a friendly assault on a hostile-held coast.

The exercise tested Podsolnukh, which was deployed in Primorye region in the Far East. A special commission was formed and engaged Podsolnukh to see preparations for the exercise and its active phase - regrouping of warships, aircraft flights, amphibious assault landing. "One radar made us see the whole picture. We saw helicopters flying from one ship to another, assault landing, maneuvers of warships and aircraft in real time," Skolotnev said.

Podsolnukh watched foreign fighter jets approach the Russian exercise from South Korea. A US aircraft flew from Japan and circled close to the Russian air border. A Russian fighter jet arrived to the area 15-20 minutes later.

The capabilities of the Russian radar triggered interest of foreign countries that have access to the sea. An upgraded Podsolnukh for export was designed in 2015.

A contract with one foreign customer for over-the-horizon Podsolnukh is being finalized. The Russian radar won an open tender of the customer in 2016 due to better characteristics against sky-wave Stradivarius designed by France and Israel.

Skolotnev said the French-Israeli radar has several vulnerable points. Podsolnukh keeps receivers and transmitters together while Stradivarius has them separated by 200 km. Besides, it cannot simultaneously detect aircraft and a big number of surface objects.

Podsolnukh can simultaneously detect over 200 sea targets and over a hundred air targets. Each target gets specific information from detection to withdrawal from the sector.

The United States and Canada have a radar similar to Podsolnukh in the range of functions and detection quality. It was designed by Raytheon Company and batch production was launched. The radar detects warships and aircraft in the 200-mile economic zone. It operates three radars - SWR-503, SWR-610 and SWR-1018. Digits mean the frequency band. SWR-503 operates in 3.5-5MHz band, SWR-610 in 6 to 10 MHz band, SWR-2018 - in 10 to 18 MHz band. There is an optimal frequency for each class of the target and the wave length should be multiple or coincide with the size of the target. Therefore, the United States produced three radars for each type of the target to reliably detect aircraft and warships of various size.

"We have Podsolnukh to deal with all the missions. Nothing but Podsolnukh can at present simultaneously detect sea and air objects on a space of 150 square kilometers in the exclusive 200-mile zone round-the-clock and in any climate," Skolotnev said.
