Tallguide 134 Ultra Low
Transmission Loss Waveguide
Used for Maritime Ship
Surveillance Radar

Ocala, Florida, February 01/Internet --- Antennas for Communications (AFC) announced today that it has completed its contract with Applications Technology, Inc. of San Diego California for the manufacture of X-band Tallguide TG134 ultra low transmission loss waveguide for the maritime surveillance radar in Hawaii. The Tallguide T134 is used to connect the AN/APS-134 radar microwave electronics to a modified high gain X-band antenna in support of a US Navy subcontract with SPAWARS. Mounted within AFC's 61-ft. diameter radome, purchased by Lockheed Martin for their FPS-117 radar contract with the US Air Force, the AN/APS-134 radar antenna is colocated within the radome with the FPS-117 radar. The Tallguide TG134 run follows a path from the electronics bay to the radome base foundation floor level.

The AN/APS-134 multimode search radar is manufactured by Raytheon (Texas Instruments) and is used as well on such surveillance aircraft as the P-3B, EP-3E, HC-130H, CP-140A (Canada; Canadian version called AN/APS-507), Atlantique (Germany/France), P-3K (New Zealand), Fokker 50 Mk 2 (Singapore), CN-235MPA (Brunei), and P-3C (South Korea).

Typical of maritime radar, sea surveillance demands ever-increasing performances from sensors and mission systems. They must be capable of detecting a very wide range of targets including submarines, inflatable boats and supertankers. To help accomplish these tasks, the Tallguide TG134 ultra low transmission loss waveguide significantly increases signal-to-noise ratio and detection range.

In order to detect targets of all sizes and in all weather conditions (in particular at all sea states), these maritime surveillance radar systems also use pulse compression, frequency agility and integration in turn, to reduce signal clutter. Digital processing then enables the classification of these targets, automatic multitarget tracking and radar image plotting allowing, by comparison with a databank, target type identification.

"In radar applications where double-path transmission loss improvements have twice the impact, Tallguide TG134 replaces WR90 waveguide with substantial radar performance increases" said Dr. Ronald S. Posner, AFC's CEO. "For the US Navy radar, approximately 2 dB double-path signal power was recovered by substituting Tallguide TG134 for 27-ft. (8.3m) WR90 waveguide."

Antennas for Communications manufactures satellite and terrestrial antennas, radomes, microwave and waveguide components and Tallguide , an ultra low transmission loss waveguide. The company serves the satellite, broadcast, communications, cable, radar, weather and government industry worldwide.
