MIMO Radar System

In collaboration with Information Systems Laboratories, the Multiple Input-Multiple Output (MIMO) capabilities were demonstrated on Telephonics’ X-band production radar and enabled simultaneous adaptive clutter cancellation and monopulse angle estimation in a small, two-phase center antenna, previously only feasible in four-phase centers. By transforming a small, electronically scanned antenna (ESA) into a much larger virtual array, MIMO capabilities enable expanding roles for smaller, Cost, Size, Weight and Power (C-SWaP) constrained platforms such as Unmanned Aerial Vehicles (UAVs). 

The Telephonics Advantage

    • Successfully developed and flight tested a MIMO-based variant on a Telephonics X-band radar
      • Real-world data validated performance
    • Unlike phased array radar which transmits a scaled version of the same waveform, MIMO radar employs waveform diversity to enable superior performance in a number of key areas

Additional Benefits

    • Higher bearing accuracy for the same array size
    • Ability to detect slower-moving targets
    • With slight modification can adopt adaptive array techniques developed for Single Input -Multiple Output (SIMO) radar including:
      • Space Time Adaptive Processing (STAP) to cancel clutter
      • STAP to suppress jammers
