The Egyptian Ministry of Defence has received into service the new 59N6E Protivnik-GE 3D early warning surveillance radar from Russia.

The 59N6E Protivnik-GE 3D early warning surveillance radar was spotted during a latest military parade in Egypt.

According to the ausairpower.net, the 59N6E Protivnik-GE is a medium/high-altitude radar is designed to acquire and track strategic and tactical planes, air-launched and ballistic missiles and small low-speed aircraft in electronic countermeasures-heavy environment and feed the resultant data to the automation systems of command posts.

The primary antenna planar array is designed for low sidelobes and backlobes – the inner sidelobes being cited at -40 dB and the average sidelobe level at -53 dB. The transmitter delivers a peak power rating of 500 kiloWatts, and a average power rating of 12 kiloWatts, with a 3 dB receiver noise figure. An IFF array is mounted beneath the primary aperture. Russian sources claim the use of Space Time Adaptive Processing (STAP) techniques, as well as adaptive sidelobe nulling.

All radar processing is digital. The 8.5 x 5.5 metre aperture planar array uses electronic beamsteering in elevation while azimuthal pointing is achieved by rotating the turntable. EU claim the ability to form up to twenty pencil beams to track precisely individual targets. The azimuthal tracking accuracy of 0.2°, elevation accuracy of 0.17° and range accuracy of 50-100 metres make this radar capable of providing midcourse cueing for a range of SAM systems.
