LN-66
The LN-66, alias AN/SPS-59(V) was an X-Band surface surveillance and short-range navigation radar made by the Canadian Marconi Company. The radar was designed to detect surface obstacles or other vessels and utilizes a slotted linear waveguide array with a 4 ft (1.22 m) antenna. The radar was used aboard a wide range of surface combatants.
The radar was widely exported under various class names and designations:
- LN-66/HP for use in the Kaman Seasprite SH-2F LAMPS I helicopter. The antenna of this variant was mounted in a 3 ft enclosed radome.
- TPS-66 is a Canadian designation for the radar in the TSQ-108 Radar/Sonar Surveillance Center;
- The CMR-85 was designed for a submarine environment.
