Plasma signal attenuation concepts and attenuation experiments in which telemetry and microwave signals are transmitted through simulated flight plasma; computations of plasma conditions about re-entry shapes show effects of body bluntness, angle of attack, velocity, and altitude on plasma and collision frequency in shock layer; signal frequencies of 10 k Mc are required to avoid sudden signal blackout during critical part of lifting re-entry flight.
