Method for plasma dynamic cancellation for hypersonic vehicles

A sensor system comprising:

• a main antenna;
• a plurality of auxiliary antennas that are circumferentially spaced around the main antenna and are diametrically opposed to one another;
• and
• a controller operatively coupled to the at least one auxiliary antenna;
• wherein the controller receives information from the at least one auxiliary antenna regarding a plasma field that inhibits sending and/or receipt of signals by the main antenna;
• and
• wherein the controller configures an electromagnetic field set up by the at least one auxiliary antenna to reduce density of the plasma field, thereby reducing at least in part inhibition by the plasma field of the sending and/or receipt of signals of the main antenna,
• wherein the at least one auxiliary antenna includes a plurality of auxiliary antennas that are circumferentially spaced around the main antenna.

A sensor system contained in a radome of a hypersonic vehicle that includes a negatively or positively charged metallic tip, the sensor system comprising:

• a main antenna;
• at least one auxiliary antenna;
• a controller operatively coupled to the at least one auxiliary antenna;
• and
• a plurality of charged plates having an opposite charge from the metallic tip that are circumferentially spaced around the main antenna, wherein the metallic tip is located distally opposite the plurality of charged plates,
• wherein the controller receives information from the at least one auxiliary antenna regarding a plasma field that inhibits sending and/or receipt of signals by the main antenna, and
• wherein the controller configures an electromagnetic field set up by the at least one auxiliary antenna to reduce density of the plasma field, thereby reducing at least in part inhibition by the plasma field of the sending and/or receipt of signals of the main antenna.
