Harris is designing and developing the Common Data Link (CDL) X-/Ku-band phased array antenna system for the next-generation destroyer, the DD(X), that is being developed for the U.S. Navy. The low-observable, high-data-rate, multi-beam antennas will be integrated into the DD(X) composite Integrated Deckhouse Assembly (IDHA). Harris also will provide integration and test support services. The Harris Phased Array Antenna has been specifically engineered to communicate error-free within the harsh shipboard Electro-Magnetic Interference (EMI) environment caused by co-located high-power search and tracking radars. The unique Harris-patented architecture provides simultaneous shipboard multi-beam connectivity with up to eight Common Data Link (CDL)/Tactical Common Data Link (TCDL) assets, all from the same phased array antenna. This capability eliminates the traditional requirement of a dedicated antenna for each data link asset. The Harris-built antennas address the challenge of limited shipboard topside space. They will be conformal-mounted into the DD(X)deckhouse superstructure and will contain no moving parts. Unlike the dish antennas they will replace, the low-maintenance phased array antenna “electronically steers” its multiple beams.
