The TPS-77 MRR is designed for ultra-low power consumption and is the most transportable version of Lockheed Martin’s successful TPS-77 product line. Latvia’s variant of this high-performing radar can be truck mounted for operation at unprepared sites or dismounted for use at fixed sites.
The radar’s multi-role single scan technology allows operators to select specific roles for the radar such as long range or medium range low-level flight surveillance (including helicopter detection) in specific sectors. As the radar rotates through each 360 degree scan, the system automatically adjusts to the operator selected mission. Changes can be easily made if the system is moved or mission is changed. Once set, no further operator inputs are required.
As with current production TPS-77s and other next generation Lockheed Martin radars, the TPS-77 MRR uses Gallium Nitride (GaN) technology in its design. The GaN technology has already been installed and tested in operational radars. Utilizing GaN, the radars high power amplifiers consume much less power, ultimately increasing reliability, lowering life-cycle costs and extending the useful life of the radar.
Lockheed Martin has produced and maintains more than 175 surveillance-range radars, all of which are operational around the world detecting targets at ranges up to 250 miles, 24 hours a day. These radars are capable of operating completely unmanned and many have performed for decades in remote, inhospitable areas and in a wide range of operational environments.
