Ship Signatures (Radar, Infrared, Acoustic)

This work supports the Navy’s interest in advanced sea platform survivability science and technology, and submarine science and technology.

  • Signature and detection prediction models
    • Predicting radar refractivity/propagation from radar clutter measurements
    • Radar and acoustic propagation modeling
    • Small craft and periscope detection models
  • Signature mitigation materials
    • Radar absorbing composites for boats
    • Periscope/mast radar absorbers
  • Acoustics: Noise mitigation technologies for small, high speed surface craft

Research Concentration Areas

  • Cost reduction for low, observable planing craft
  • Electromagnetic signature models
  • Signature mitigation materials
    • Electromagnetic (EM) performance for combatant craft limited by available hull/superstructure materials
    • EM properties optimized to improve the performance of integrated EM sensors (e.g. communications, radar) as well as minimizing the signature of the vessel at radio frequency (RF) and optical frequencies

Research Challenges and Opportunities

  • Physics-based detection models (RF/optical)
  • Improved environmental models of sea/air interface
  • Signature mitigation materials
    • Thin/lightweight survivable multispectral/multifunction materials
    • Balance radio frequency/optical performance
    • Radar absorbing ballistic and structural composites
    • Radar transparent composites
  • Acoustics
    • Develop physics-based airborne and underwater acoustic signature and detectability prediction tools for high-speed planing craft
    • Develop mitigation technologies within mission constraints
