In order to evaluate the effects of a nuclear disturbance of the ionosphere on UHF satellite communication, barium ions were released in the ionosphere. The test, nicknamed STRESS, was sponsored by the Defense Nuclear Agency. The drift of the barium ions across the magnetic field lines cause the ions to consolidate in rods, or sheets, causing diffraction of radio waves passing through the ionosphere. AFALs Satellite Communication System aboard a C-135 type aircraft was flown in the shadow of the cloud and communicated through the ionospheric disturbance to the LES 89 UHF satellites. Measurements were made of the fading characteristics and bit error rate performance when communicating through the ionospheric disturbance.
