This presentation shows work being done by Duotech for a Radar Warning Receiver (RWR). This presentation was given at the 2016 F-16 TCG in Ogden, UT. Watch video of the presentation here > http://duotechservices.com/radar-warning-receiver-briefing-f-16-tcg-wwr

1. Outpacing Obsolescence

2. Current Conditions
• OEMs pushing new systems beyond current demand
• Significant customer demand for current system
sustainment
• Results: lack of support and soft upgrades
The Duotech Solution
• Sustain current systems
• Provide alternative to OEM system replacement push
• Affordable upgrades
• Sustainable, long-­term support
F-­16 Radar Warning Receiver

3. • Sustain current systems via repair
• Leverage advanced technology to
provide maximum value
What does this
mean?_____________
• Minimal modifications to current
systems
• Maximum capability and
sustainability improvement

6. Preparing for Your Installation
• Low sensitivity
• Identify limitations
• System technical and installation documentation review
• Assembly at laboratory
• System characterization at laboratory using emitters
simulator
• System ground and flight testing to be scheduled
• Current installations need to be characterized
Activities
Relevant issues
Low RWR/radar ratio for current airborne fire
control radars
Limited narrow pulse width discrimination

7. ALR-­69 Sensitivity Upgrade:
BASIC SOLUTION
Basic Solution: Upgrade E/J Amplifier Detectors
• Other LRUs remain the same
• No External cable modifications

BASIC SOLUTION

9. ALR-­69 sensitivity upgrade
• Improved situation awareness and early
warning by detecting enemy radars
before they detect you
• The Increment in detection range,
compared with original system, is
according to operational requirement.
• Pilot resource management and
awareness alarms have to be considered.
• Increasing sensitivity to 2x the detection
distance
• Improved false alarm rate
• Increased probability of detection for
narrow, weak pulses
• The replacement of old components
improves the logistic capabilities

10. Right Product – Right Time
• Importance of the RWR system
• OEMs pushing expensive upgrades
• Invalidate current repair structures
• Overhaul of current test equipment and processes
• Your requirements should dictate the solution
• Long-­term sustainment
• Easy, effective capability enhancements
• Low total cost of ownership
• Responsive, receptive support provider – Duotech!
