Anti-radar based on metasurface

Area of Science:

• Electrical Engineering
• Electromagnetics
• Radar Systems

Background:

• Multi-static radar (MSR) systems collect target echo signals from multiple receivers for precise localization.
• MSR technology is widely used in sensing, military, aviation, and aerospace due to its robust localization and tracking.
• The distributed nature of MSR makes it challenging to counter effectively.

Purpose of the Study:

• To propose a novel anti-radar methodology to counter advanced multi-static radar (MSR) systems.
• To develop a cost-effective, miniaturized, and low-complexity electronic countermeasure (ECM) system.
• To demonstrate exceptional concealment and deception performance in non-cooperative and dynamic ECM scenarios.

Main Methods:

• Designing physical characteristics of space-time-coding metasurface (STCM).
• Developing adaptive and robust electronic countermeasure (ECM) control strategies.
• Implementing a prototype STCM-based anti-MSR system for validation.

Main Results:

• The proposed STCM-based ECM system exhibits flexible control capabilities.
• Exceptional concealment and deception performance were achieved under dynamic and non-cooperative scenarios.
• Successful neutralization of various MSR technologies was demonstrated by the prototype system.

Conclusions:

• The developed STCM-based methodology provides an effective solution for countering MSR.
• The system is cost-effective, miniaturized, and low-complexity, suitable for practical anti-MSR applications.
• This research is expected to significantly impact future anti-MSR strategies and technologies.
