High Accuracy Direction Finding (HADF)

Operational requirement
Precise direction finding

• To support accurate Tactical Situation Awareness
• To enable Passive Targeting

Vigile solution

• Wide Band Interferometer Array each covering 90° of azimuth
• Bi-polar antennas
• Wide Band MMIC phasemeter
• Pulse-to-Pulse DOA measurement
   

Key features:

• Sub-degree DF accuracy on E to J bands
• 100 % Probability of Intercept (POI)
• All polarisations (H, V, LHC, RHC)
