About this technology
Overview
NASA Goddard Space Flight Center has developed technology based on interference of a stable optical source with itself. A single source is split into multiple paths. Incoming RF signals are modulated onto individual paths of optical signal. These individual paths are then recombined to correlate the RF signals to each other. The basic system achieves coherent detection and correlation. Modifications to the basic system can be implemented as necessary to enhance system performance characteristics while maintaining reliability. This includes improving system signal-to-noise, stability, correlation detection, and speed.
