MOTHR is a new generation of multi-function radar that can detect, track, define, communicate, analyze and more, simultaneously.The knowhow embedded in MOTHR is new methods and systems for information processing developed by Russian mathematicians and software developers, the radar that utilizes the effect of electromagnetic beam bouncing off the ionosphere.

MOTHR features:
• Detect, track and classify airborne vehicles (include STEALTH technology)
• Monitor military and commercial aircraft day-to-day operations
• Identify potentially dangerous targets
• Detect aircraft take off in small and large formations
• Detect military aircraft movement between bases
• Inform command center about detected and being tracked objects

MOTHR is designed with extended range to determine the coordinates and velocity parameters of a broad range of aerial targets (including stealth-technology aircraft).It provides situational awareness, offers high reliability and quality of the output information. Even under deliberate jamming of various kinds and intensity, the radar system cannot be rendered blind by electronic warfare systems as it constantly switches to jam-free frequencies in automatic mode.
