MARS-L is Altimus-Tech's mobile L-band radar that combines primary-surveillance and secondary-surveillance channels on a one-vehicle system. The manufacturer markets it for aircraft detection, interrogation, track generation, radar-data distribution, and air-defense support, including use as a low-altitude surveillance radar, radar-field gap filler, and target-acquisition sensor for upgraded Soviet-legacy surface-to-air missile packages.
MARS-L combines a primary radar picture with secondary-radar interrogation so the operator can correlate detected aircraft with transponder replies and flight data. Altimus-Tech presents the system for air-defense coverage, terminal-area flight assurance, radar-troop gap filling, and target-acquisition support for anti-aircraft missile units.
The manufacturer lists automatic jamming monitoring, PSR frequency shifting across 250 steps, digital signal processing, and passive-interference rejection through digital MTI and adaptive clutter mapping.
The system can acquire and process air-situation data from another radar, build multi-radar tracks, distribute the air picture, and record radar data.
Altimus-Tech lists a one-vehicle configuration, ten-minute deployment or teardown by qualified personnel, and road speeds of 25-40 km/h off road and 40-60 km/h on highways.
Altimus-Tech markets MARS-L as a surveillance and target-acquisition radar that can work with height-finder equipment and upgraded Soviet-legacy surface-to-air missile packages.
