Duotech Services and Tactical Air Support
Fighter squadrons face shortfalls in Adversary Air Support (AdAir) for combat training due to budgetary shortages and a lack of truly advanced threat replication. Tactical Air Support and Duotech Services are poised to provide training assets that represent current threat capabilities with the F-5 and NEMESIS® RADAR at a very low-cost point. Tactical Air Support’s F-5 platform, with Nemesis RADAR installed, is the best AdAir solution in the market today, with an unrivaled combination of performance, sustainability, safety, and growth potential. In a joint development program, Tactical Air Support, and Duotech Services have designed a purpose-built RADAR to support the AdAir market by presenting a solution that is:
- Highly
capable utilizing modern RADAR techniques - Ability to quickly add additional RADAR capabilities to meet AdAir training requirements
- Threat replication via unclassified and classified means
- Fast, highly upgraded aircraft fly realistic adversary intercept profiles, offering mission-critical situational awareness and assessment capabilities
- The most sustainable and maintainable AdAir platform for greatest uptime of both aircraft and RADAR
Real World Threat Replication
FAAC Incorporated is the leader in simulation for training and research. Duotech’s NEMESIS RADAR is integrated with FAAC’s real-world threat replication software. FAAC Zone Acquisition Process (ZAP) software provides high-speed missile simulations capable of running much faster than real-time with limited resources.
ZAP relies on faster-than-real-time 5-DOF embedded weapon simulations to determine trajectory parameters. The ZAP trajectory simulations match the available intelligence 6-DOF simulations. This results in highly accurate display information over the entire flight envelope.
ZAP provides reliable shoot cue information and allows a meaningful allowable steering error to be displayed. After launch, ZAP computes the current time to impact using actual tracked target maneuvers and continually assesses the shot quality and provides an indication of predicted endgame success.
Duotech’s Ultra Wide Band waveform design and generation provide leading threat replication capability. Direct synthesis and receiving allow for training options previously unavailable.
Tailor Made Mechanically Scanned Antenna (MESA) RADAR
- NEMESIS is a tailor-made Mechanically Scanned Array (MESA) RADAR meant for aircraft which cannot house a full DELTA RADAR
- NEMESIS will conform to current aircraft avionics bays, standard rack structures and utilize existing power and cooling
- NEMESIS can employ an array aperture optimized for the current aircraft radome, thus no costly structural modifications required
- Utilizes a proven X Band Solid State Power Amplifier technology for a higher mean time between failure, higher clutter improvement factor and lower out of band emissions compared to tube-based amplifiers
- Duotech’s Receiver / Processor LRU, also utilized in the DELTA RADAR, utilizes modern processing technology to optimize RADAR performance
- NEMESIS upgrades and retrofits eliminate any obsolescence or supportability issues
- Fully supportable with Duotech’s ARTES ATE and our proven depot-level repair expertise spanning four decades
