AbstractPassive detection and classification of missiles, aircraft, and units with internal combustion engines and rocket motors beyond the visual horizon is a capability of substantial tactical significance. Electromagnetic radiation from ions in engines has been identified as a potentially exploitable emission. Ions from combustion have been measured with relatively modest equipment in previous studies. Exploitation of these signals for detection and tracking warrants further investigation. Analysis has also determined that acoustic and mechanical processes in combustion chambers and turbines modulate the ion signals in a deterministic manner that makes the engine type classifiable. The work proposed confirms these sources with additional analysis and quantitative measurements. The upgrading of existing equipment to operate in real-time will support data collection that is intended to define the source of the emissions. The team proposed has extensive experience in developing systems of the kind required.
