# Recursive Electronic Warfare **Entity class:** Concept **Research spine:** [[research/Chronology of Signals, Silos, and Sovereign Software - Research|Chronology of Signals, Silos, and Sovereign Software]] ## Definition Recursive electronic warfare is the cycle in which reconnaissance discovers a sensing system, countermeasures defeat it, the adversary adapts, and collection begins again. ## Chronological Proximity The cycle was visible from the 1942 bomber-stream breakthrough through the 1943–1945 jamming and counter-jamming contest. ## Relational Proximity [[wiki/Passive Electromagnetic Reconnaissance|Passive reconnaissance]], [[wiki/Radar Countermeasures|countermeasures]], and adversary adaptation form a feedback system rather than a one-time technical solution. ## Collection Routes [[collections/The Civilian Intelligence Marketplace|The Civilian Intelligence Marketplace]] · [[collections/Terrorism, Counterterrorism, and the Intelligence Environment|Terrorism, Counterterrorism, and the Intelligence Environment]] · [[wiki/Signals, Silos, and Sovereign Software|Signals, Silos, and Sovereign Software]] ## Sources / Provenance - [[research/Chronology of Signals, Silos, and Sovereign Software - Research|Chronology of Signals, Silos, and Sovereign Software - Research]].
