AN/FPS-19

The AN/FPS-19 was a long range, high power L-Band early warning radar developed for the NORAD DEW Line in Alaska and Canada.

The radar antenna was buildt by Bendix and used two antennas in back-to-back configuration, fed by two transmitters fitted with the Raytheon 5J26 magnetron. Both main reflectors were shaped as a single curved parabola with a squintless feed (similar to Type 1022 radar). One antenna formed a pencil beam with a tilt of 2 degrees for long-range detection in low elevation angle. The other one formed a cosecant squared pattern with a tilt of 6.5 degrees.

The radar electronic group was based on the earlier AN/TPS-1D made by Raytheon.

In the late 1980’s, the AN/FPS-19’s were replaced by the AN/FPS-117.
