Retrodirective Arrays for Coherent Transmission (ReACT)

Abstract

Worldwide advancements in signal processing and electronics have decreased the effectiveness of single-platform, power-based Electronic Warfare (EW) as a viable technique in the future. The goal of the Retrodirective Arrays for Coherent Transmission (ReACT) program was to develop and demonstrate the capability to combine distributed mobile transmitters to direct high-power spatially resolved radio frequency (RF) beams to a single location. ReACT provides this capability by synchronizing multiple distributed transmitters to form a much larger effective array than a single aperture. The key technical challenge was to synchronize distributed and moving transmitters while compensating for platform motion and vibration. The ReACT system sensed the target's emissions and then optimally configured the ReACT transmitters to focus on the area of interest. Technologies from this program transitioned to the Air Force and Navy.
