The RAT 31DL is a solid-state active phased array radar with monopulse antenna with 42 rows of 42 Tx/Rx modules of which 24 boosted, each with 2 kW output power. The 360 ° search is performed with four independent beams in the L band at 6 rpm, the vertical pivoting of the beams is done by means of electronic phase shift of the 42 rows feeding ...
The Ground Master 400 (GM400) is a mobile long range radar system manufactured by Thales (formerly by Thales-Raytheon Systems). [1] GM400 is a fully digital active electronically scanned array long-range air defense 3D radar, offering detection from very high to very low altitudes.
Rho-Theta methodology is a key component in Area Navigation (RNAV). [1] The term "Rho-Theta" consists of the two Greek letters corresponding to Rho and Theta: [2] [3] [4] Rho (Greek ρ) as a synonym for distance measurement, e.g. Rho would be the equivalent to the English abbreviation "R" for Range
The Ground Master 200 Multi-Mission (GM200 MM) is a family of medium-range radars manufactured by Thales Nederland. [1] [2] Benifiting from the technology of the land-based Ground Master 200 and naval NS100/200 radar systems, this series was developed by the Dutch subsidiary for, and in consultation with, the Royal Netherlands Army (RNLA).

The AN/SPS-67 is a solid-state replacement for the AN/SPS-10 radar, using a more reliable antenna and incorporating standard electronic module technology for simpler repair and maintenance. The AN/SPS-67 provides excellent performance in rain and sea clutter, and is useful in harbor navigation, since the AN/SPS-67 is capable of detecting buoys ...
The system has two operating modes: medium range up to 150 km (81 nmi) at 27 RPM and long range up to 250 km (130 nmi) at 13.5 RPM. The radar mainly designed for light frigates, corvettes and ships such as Landing Platform Docks (LPD). SMART-S Mk2 is designed to support full performance of surface to air missiles (SAM), such as the RIM-162 ESSM.
Beam steering is a technique for changing the direction of the main lobe of a radiation pattern. In radio and radar systems, beam steering may be accomplished by switching the antenna elements or by changing the relative phases of the RF signals driving the elements. As a result, this directs the transmit signal towards an intended receiver.
The boat uses MRK-50 Topol (Snoop Tray) surface search radar, a Magnavox satellite navigation system for communications, with a Type 921A electronics warfare suite. Nabajatra has eight 533 mm (21 in) torpedo tubes which can launch a complement of 14 heavy weight ET-31 anti-ship torpedoes and ET-40 anti-submarine torpedoes.
