Study of Methods of Analysis of Spaced Receiver Drift Records

Abstract

A review of the close-spaced receiver method for the investigation of the movements of small scale ionospheric is made with special reference to the method of analysis. The deficiencies of the full correlation method are pointed out. Results of multi-aerial experiments, carried out to test some of the assumptions underlying the full correlation method, are given. One of the experiments, in which two different geometries of aerial arrays are simultaneously used, showed that the axial ratio and orientation of the characteristic seven receiving aerials are deployed in a straight line, it is found that the fading velocity shows marked dependence on the aerial spacing., This shows that the assumption that the fading statistics are stationary is not valid in practical situations.
