Cobham Advanced Electronics plans to demonstrate late this summer or in early fall a solid-state radar transmitter that could replace the older vacuum-tube designs of current transmitters—as well as those of airborne and land-based radars of the other services.
The initial target for the new transmitter is the SPY-1 passive phased-array radar built by Lockheed Martin since the 1970s as a key component of the Aegis combat system, in service on board Ticonderoga (CG-47)-class cruisers and Arleigh Burke (DDG-51)-class destroyers, and long supported by Cobham.
For the full duration of the Aegis program, Cobham has provided the electronic network that links the SPY-1 antenna and transmitter, which is built by Raytheon. That network includes waveguides that manage power flow, cabling, cooling elements, packaging, and other components. Cobham also provides antenna array panel assemblies to Lockheed Martin for the Block II surface electronic warfare improvement program (SEWIP), a long-term upgrade to the Navy’s SLQ-32(v) shipboard electronic warfare system.
