Coho

Abstract

The Coho program developed advanced signal processing technologies and techniques for future Radio Frequency (RF) systems. These systems created an asymmetric advantage for tactical operations in anti-access/area-denial environments by extending the real-time operating bandwidth of tactical signal processing, underpinning the ability of U.S. and Allied Forces to accurately orient and beneficially maneuver in the electromagnetic spectrum. Coho provided ultra-wideband RF signal detection and recognition capabilities in a form factor suitable for tactical platforms. Coho sought to provide capabilities for multiple mission areas. These capabilities included (1) surveillance: combining wide operating bandwidth with noise isolation for background electromagnetic search in the low signal to noise ratio environment, (2) filtering: isolating signals based on modulation features to process signals in the presence of co-channel interference, and (3) localization: supporting low-latency execution of multi-aperture processing for discrimination of signals based on angle of bearing. Technology from Coho transitioned to the Services.
