Summary: | SRI International provided radio and radar support for a number of government programs, especially investigations of the effects of the earth's ionosphere on Air Force systems. Investigations at equatorial, mid, and polar latitudes were carried out using a variety of optical, radar, and radio instruments. A network of ground-based scintillation receivers was established to provide real-time diagnostics and communication outage alerts and forecasts. Barium releases and resulting striation structures (or lack of) were observed with scintillation receivers and HF radar. Ionospheric corrections for GPS tracking of re-entry vehicles were performed for the equatorial ionosphere, and a number of auroral ionosphere experiments were carried out at Sondrestromfjord, Greenland. A scintillation diagnostic array was designed for the HAARP program. Various GPS sensor calibrations and signal analyses were performed. |
