Localization of a Power-Modulated Jammer

Area of Science:

• Radio Communications
• Signal Processing
• Cybersecurity

Background:

• Jamming poses a significant threat in critical radio communication scenarios.
• Existing detection, localization, and mitigation techniques are vulnerable to advanced jamming methods.
• Counter-jamming strategies are crucial for maintaining communication integrity.

Purpose of the Study:

• To introduce a novel mathematical model for a power-modulated jammer.
• To analyze the localization error introduced by this new jammer model.
• To compare the performance against standard power-constant jammer models.

Main Methods:

• Development of a new mathematical model for power-modulated jamming.
• Comparative analysis of localization errors between power-modulated and power-constant jammers.
• Simulation and theoretical evaluation under varying shadowing effects.

Main Results:

• Power-modulated jammers can render standard localization techniques ineffective.
• High localization precision is achievable for constant-power jammers, even with strong shadowing (σ ≈ 6 dBm).
• Power-modulated jammers exhibit significantly larger localization errors than constant-power jammers, even with weak shadowing (σ < 2 dBm).

Conclusions:

• The proposed power-modulated jammer model effectively disrupts radio signal localization.
• This research highlights the limitations of current localization techniques against adaptive jamming.
• The findings pave the way for developing more robust counter-jamming and localization strategies.
