Analog Optical Signal Processing (AOSP)

The Analog Optical Signal Processing (AOSP) program objectives are to significantly enhance the performance of and enable entirely new capabilities/architectures for tactical and strategic radio frequency (RF) systems by expanding the dynamic range (bandwidth and time-bandwidth limits by a factor of 1000 or more) through the introduction of analog optical signal processing components into the system front ends.

The most challenging target detection problem is a stationary target in a cluttered environment...

Specific components developed address the three basic functions of an advanced RF system: (1) Interference Mitigation - i.e., high quadrature (Q) tunable filters (spatial, spectral, and temporal); (2) Signal Detection - high performance all optical signal processors (time bandwidth products > 200,000, dynamic range > 100dB); (3) Optical Arbitrary Waveform Generation (>12 bits resolution @ 10 GHz bandwidth). The operational impact of the most promising device technologies will be demonstrated in a system-relevant context. Ideally, all three types of components will be integrated into a single relevant prototype demonstration, for example, an electronic warfare context wherein jammers are mitigated, signals are detected, and an appropriate response is generated.
