METHOD

  Based on user's choice of the

• aircraft
• antenna
• antenna placement
• antenna characterictics
• pattern cuts

• builds propagation paths from radiating
  source to given observation points in
  far-region
• classifies diffraction mechanisms and
  computes all geometric characteristics
  required for EM analysis
• computes and integrates field contributions
  by different diffraction mechanisms
• displays computed results graphically

WHAT does DOVA do?

• DOVA system utilizes high-frequency and differential geometric techniques to compute radiation patterns of platform-mounted antennas.
• Realistic CAD-generated models are used in computations

BENEFITS

• high efficiency computer simulation reduces cost of experimentation in search of the most effective operational environment
• faithful CAD representation of the platform geometry results in higher accuracy of computed results
• different types of antennas can be analyzed
• user-interactive antenna repositioning and dynamic modeling are supported, thereby allowing to play ``what-if'' scenarios with visual feedback

FEATURES

• real-time performance
• interactive environment with user-friendly interface
• powerful visualization components that allow
  • to view and manipulate 3-D models and computed propagation paths
  • to view antenna radiation patterns in Cartesian and Polar coordinates.
• extensive on-line help
