AN / SPY-6

from Wikipedia, the free encyclopedia

The AN / SPY-6 is a ship-based multifunction radar of US -Konzerns Raytheon and is based on Active Electronically Scanned Array (AESA) s. In addition to tracking all types of air targets, it is also used on warships to capture ballistic missiles and for anti- missile defense . The radar system has a modular structure and its size can be scaled. It is in various configurations from 2023 ( IOC ) on multiple ship classes such as the guided missile destroyers of the Arleigh Burke-class destroyer of the United States Navy to be used.

description

The architecture of the SPY-6 is based on the so-called "Radar Modular Assemblies" (RMAs). Each of these approx. 70 cm large cube is a self-contained radar complex with 144 transceivers , which can be interconnected with practically any number of other RMAs to form an even more powerful radar system. The SPY-6 is based on AESA technology, which has considerable advantages over conventional radars in terms of range, interference resistance and flexibility. In addition, it is one of the first ship-based systems to use gallium nitride- based semiconductor components in the high-frequency section on a large scale. Compared to the gallium arsenide previously used in AESA designs, these enable a significantly higher transmission power and bandwidth . These and other new technologies have increased the sensitivity by up to 30 times compared to the previous system AN / SPY-1 and the transmission power by around 35 times. Like its predecessor, the SPY-6 works in the S- band at 2 - 4 GHz , which means that high ranges can be achieved and certain stealth techniques are reduced in their effectiveness. However, this happens at the expense of accuracy, which is why semi-active guided missiles such as the SM-2 or ESSM require an additional X-band (8-12 GHz) fire control radar for target lighting on the final approach. However, thanks to their on-board active radar systems, newer guided missiles such as the SM-6 and ESSM Block 2 can do without this support and can be steered to the target purely with the SPY-6. Due to the high transmission power and agility of the GaN transmitter, applications in the area of ​​offensive electronic countermeasures with the SPY-6 are also conceivable.

variants

AN / SPY-6 (V) 1

This variant is also known as "Air and Missile Defense Radar" (AMDR-S) and is to be installed on all new destroyers of the Arleigh Burke Flight III class . Four antenna groups with 37 RMAs each are used. This is the most powerful radar complex of the SPY-6 series with a very long range.

AN / SPY-6 (V) 2

Also known as "Enterprise Air Surveillance Radar" (ESAR) / "Rotator Radar". Here 9 RMAs are mounted on a rotating platform, so that periodic 360 ° coverage can be achieved with few modules and low costs. This system is to be installed on all amphibious landing ships of the San Antonio Flight II class and to replace the AN / SPS-48 E and AN / SPS-49 (V) 5 on all aircraft carriers of the Nimitz class .

AN / SPY-6 (V) 3

Also known as "Enterprise Air Surveillance Radar" (ESAR) / "Fixed Face Radar". This complex for the Gerald R. Ford class aircraft carriers consists of three antenna groups with 9 RMAs each.

AN / SPY-6 (V) 4

This variant is also known as "Air and Missile Defense Radar" (AMDR-S), but only has 24 RMAs per antenna group and is intended to replace the AN / SPY-1D on destroyers of the Arleigh Burke Flight IIA class.
