Flight Line Phase Noise Tester (FLNT) for Radar Systems
Features
- The integrated components of the FLNT automatically make the required phase noise measurements, determine pass/fail, and display the results on the computer.
- ATTI’s Flight Line Tester can test LRUs to the required Phase Noise Levels.
- LRUs can be tested on the aircraft, or in a back-shop.
- Failing LRUs can be sent for repair with accurate identification of the fault.
Phase Noise Test Requirements
- Elevated phase noise reduces Doppler radar system target detection.
- Reference paper published at the Military Sensing Symposium Tri-Services Radar, July 2014 detailed the impact of phase noise on target detection: “Modeling the Effect of Phase Noise on Pulse Doppler Radar Target Detection”.
- Modeled results confirm that even small increases in phase noise have significant impact on target detection.
- ATTI is in development of a diagnostic tool based on the video technique that:
- Acquires test point data coincident with performance testing
- Uses an automated signal capture and bounds check to validate diagnostic waveform criteria
- Utilizes fault signatures for the isolation of failed components
- Continuously improves the diagnostic callouts based on actual test and effective repair experience
