SYSTEMS AND METHODS FOR COMMUNICATING AND SENSING THROUGH PLASMA

Smart overview of the Invention

A system has been developed to enhance communication for vehicles, such as hypersonic aircraft and spacecraft, that experience a plasma sheath at high speeds. The plasma sheath, formed by the vehicle's rapid movement through the atmosphere, can disrupt communication signals, leading to blackouts. The proposed solution involves a communication device equipped with a matching layer that interacts with the plasma to facilitate signal transmission.

Components of the System

The system consists of several key components:

• Matching Layer: Positioned on the communication device, it generates a resonant frequency that corresponds to the plasma sheath.
• Modulator: This component produces electromagnetic waves that modulate the resonant frequency, enabling effective communication.
• Control Unit: It manages the modulator's operations, ensuring optimal performance during communication attempts.

Functionality of the Matching Layer

The matching layer serves as a resonator that stabilizes the resonant frequency around 2 GHz. This stabilization is crucial because it allows for reliable communication despite the presence of plasma. The layer is typically made from electrically insulating materials and can cover various parts of the vehicle's communication device or even its entire surface.

Communication Strategy

The method of communication takes advantage of zero crossings in the resonant frequency. By timing transmissions at these points, where interference from the plasma sheath is minimal, higher frequency signals (such as those above 30 GHz) can be sent and received effectively. This approach minimizes disruptions caused by the plasma and enhances overall communication reliability.

Applications and Benefits

This innovative system is particularly beneficial for military and commercial applications where uninterrupted communication is critical. By mitigating blackouts caused by plasma sheaths during hypersonic flight, it ensures continuous operation of advanced vehicles. Additionally, it offers protection against potential jamming and microwave attacks, further enhancing its utility in sensitive operations.
