Low Probability of Intercept / Low Probability of Detection (LPI/LPD) RF Systems Fundamentals Training by Tonex
Built for engineers and mission planners, this program demystifies how modern RF systems stay hidden while staying connected. You’ll dissect the physics, architectures, and tactics that let signals blend into noise, slip past thresholds, and outmaneuver agile receivers. Security stakes are high—communications that reveal themselves can expose assets, missions, and people. Strong LPI/LPD design shrinks the cyber attack surface by reducing exploitable emissions, limiting traffic analysis value, and frustrating signal-enabled intrusion paths. You’ll connect RF stealth principles to cybersecurity operations, red-teaming perspectives, and resilient C2, translating theory into practical design and operational guardrails for contested environments.
