JT-101: Introduction to Joint MTN Operations (Link-16, US Members, FOUO) 2025 Practice Test - Free Joint MTN Operations Practice Questions and Study Guide

Link 16 jam resistance is primarily defined by the concepts of link margin and range ratio. Link margin refers to the difference between the received signal strength and the minimum required signal strength to maintain a reliable data link. A higher link margin indicates better communication resilience against jamming and interference, as the system can maintain communication over varying conditions.

The range ratio involves comparing the effective communication range to the jamming range, determining how well the system can operate under jamming conditions. A higher ratio suggests that Link 16 has robust capabilities against jamming, as it can effectively communicate over a greater distance relative to the interference it might encounter.

Understanding these two metrics—link margin and range ratio—provides insight into the overall resiliency of Link 16 communications in contested environments, as they both contribute to the effectiveness of maintaining situational awareness and command and control capabilities under potential electronic warfare conditions.
