Design and Use of a Phase-Sweep Interferometer for the Study of Radio Star Scintillations in the Auroral Zone.

The usefulness of the phase-sweep technique in interferometers designed to record radio star signals is discussed. Interferometers of this type have been built for use at frequencies of 223 and 456 Mcs., and their electronic design is explained in some detail. The report also includes a discussion of the automatic data processing system which has been designed to operate in conjunction with the interferometers in the analysis of the amplitude scintillation of radio stars.Air Force Contract No. 30(635)-2887 Project No. 5535 - Task 45774 Rome Air Development Center, Griffiss Air Force Base Romej New YorkList of Figures -- Abstract -- Introduction -- Total Power Interferometer -- Phase-Sweep Interferometer -- 223 Mes.
