Splet06. feb. 2024 · Abstract: The present invention relates to a system for resolving phase ambiguities in phase rate of change (PROC) measurements of a long baseline interferometer (LBI). The system includes an LBI having a first antenna and a second antenna positioned on a vehicle to receive the RF signal transmitted by the RF emitter, … SpletA new interferometer is being designed at Cambridge to study the Cosmic Background Radiation on angular scales of a few arcminutes to one degree at a sensitivity of a few μK. Contributions to the observed antenna temperature are expected from the atmosphere, but its effect is not well understood.
