Sea Applications

Aims

The AIMS antenna group is comprised of an antenna, antenna position programmer and a below-deck control unit used to locate and identify aircraft as friend or foe. The AIMS antenna consists of 64 radiating elements arrayed in a circle (at right in black) and uses Eccostock SH around the ship's mast. Unlike conventional IFF systems, which employ mechanically rotated antennas, the AIMS antenna elements remain stationary while the beam is steered electronically to scan a full 360 degrees around the ship. The beam can also be positioned selectively in any direction within microseconds and has a continuous scan rate of up to 90 revolutions per minute.  AIMS is used on U.S. Navy CG 47 class cruisers, DDG 51 class destroyers, LHD 1 class helicopter assault ships, LPD 17 landing platform docks, and the CVN 68 class aircraft carriers.

Sea Based X-Band Radar (XBR) & Ship Based Dual S-Band CJR

Eccosorb GDS/SS6M was used to absorb stray signals bouncing around inside the TRIMM (transmit receive integrated microwave module) on the dual s-band radar systems for the ship based CJR program as well as the sea-based x-band XBR program.  The TRIMM contains a highly integrated MMIC module designed and manufactured by Raytheon. This MMIC module contains MMIC power amplifiers, attenuators, low noise amps, phase shifters etc... and when integrated into the TRIMM stray signals caused system problems.  XBR is an integrated surveillance and ballistic missile data collection system to support U.S. treaty monitoring activities that will be stationed at Adak Island in the Aleutian Islands of Alaska.
