Lockheed Martin of Bethesda, Maryland USA, recently completed a successful site acceptance test of a TPS-77 Multi-Role Radar (TPS-77 MRR). The site acceptance testing marks the on-time delivery of the first of three radar systems to the Ministry of Defense of the Republic of Latvia.
The TPS-77 MRR, the latest version of Lockheed Martin’s line of surveillance radars that utilizes the company’s multi-role single scan technology. This technology allows operators to simultaneously select multiple missions for the radar, such as long-range or medium range low-level flight surveillance. With each 360-degree scan, the system automatically adjusts to the chosen mission. According to Lockheed Martin, users can easily make changes if the system is moved or mission is altered. However, once set, no further operator inputs are needed.
Lockheed Martin Radars Use GaN Technology
As with the current production TPS-77 systems and other next-generation Lockheed Martin ground-based air surveillance radars, the TPS-77 MRR utilizes Gallium Nitride (GaN) technology. The GaN technology enables more efficient power amplifiers, which results in improved reliability, and extends the useful life of the radar.
The company designed the TPS-77 MRR for ultra-low power consumption, and says that the systems that they delivered to the Latvian Ministry of Defense are the most transportable version of the company’s TPS-77 product line. The newly delivered systems can be truck mounted for operation at remote sites or dismounted for use at fixed locations.
The TPS-77 MRR the Defense Ministry’s low-level flight surveillance and identification capabilities, thereby enabling its armed forces to make more informed and efficient actions in response to modern threats.
