Individual IFF devices, based on polymer emitters on flexible substrates, have been evaluated to determine range of activation and observation, performance under extreme environmental conditions, and emitter intensity decay as a function of multiple activations and time. Key results include observation at distances in excess of 700 meters and device functionality in a temperature range from -40 0C to 71 0C. From data obtained in the development and testing of the individual antifratricide devices, a vehicle version is developed with the purpose of mitigating air-to-ground fratricide. A rudimentary prototype is developed and tested, followed by an improved, more powerful version. Field tests include establishing limits for activation and observability. Finally, the emission is captured and graphically represented as a function of time. Key results include observation at distances in excess of 9.5 km and demonstration of remote activation. An area for further research using quantum dots down conversion is offered. Quantum dots down conversion could be used for wavelength tuning of the polymer organic light emitting material.
