Jamming Evaluation Tool

JET is a GUI driven simulation tool that evaluates the impact of jamming on transponded satellite communications and estimates the benefit of traditional anti-jamming (AJ) measures including frequency hopping, partial payload processing, and antenna-based AJ approaches.

Features

JET is a high level link budget tool that estimates the per terminal and aggregate impacts of jamming, and allows the user to assess the tradeoffs and benefits associated with the use of a protected satellite system. Features include:

• JET allows the ability to save, recall, and easily change any parameter to see impact of any variable on system performance under jamming
• Graphical channel/jammer plot shows location and magnitude of jammer
• JET outputs shows benign and jammed per-terminal data rate, Pr/No, link margin and aggregate results for entire transponder
• JET calculates benign and jammed transponder bandwidth efficiency (b/s/Hz)

Applications

JET supports high level system design trades related to when and how to the utilize commercial versus protected satellite resources, including:

• Estimating the impact of jamming on commercial satellite systems
• Estimating the benefit & resource cost of protected verses commercial satellite systems in the presence of jamming
• Designing a system to incorporate some or all AJ features of a protected satellite system
• Evaluating how to divide user and network traffic between protected and commercial satellite systems
