SSR
Secondary Surveillance RadarNEC's Secondary Surveillance Radar is an advanced Mode S/Mono-pulse Secondary Radar (MSSR) for Enroute and approach control area.
NEC has developed the unique system architecture focusing on maintainability and future logistic supports that improve system re-configuration and enable system lifetime extension without major hardware changes.
Over 12 years of experience of the Mode-S/MSSR development provides our customers with higher performance radar in high density air traffic control environment.
The Mode S capabilities such as selective interrogation and data link offers the customers safer and more effective air traffic control services.
- ICAO standard mode-S model available
- High performance Mono-pulse technique
- Redundant and fault tolerant configuration
- Easy to use and to maintain
- Safe and easy replacement and repair
