Variable external structures on systems for signature management

A radio and/or optical frequency signature management and calibration system comprising:

• one or more radio and optical frequency emitter sources;
• one or more radio and optical frequency receiver destinations;
• and
• a target system comprising:
• a power receiving, generation, distribution, storage and control subsystem;
• a propulsion control subsystem;
• a flight stabilization and control subsystem;
• a communications subsystem;
• a command and control subsystem;
• a payload management subsystem;
• a structure management subsystem;
• a sensor collection, reporting, and feedback subsystem;
• and
• a mission tasking management subsystem;
• wherein said one or more radio and optical frequency emitter sources comprises an external radio and optical frequency structure mesh shield comprising gaps that are spaced to achieve total reflection in order to mimic a radar return of a solid object while still allowing for air to flow through said external mesh shield to enhance aerodynamics, reduce drag, and blend its electro-optical/infrared signature with the background environment.
