Abstract : Field measurements were made over a period of one year (March 1962 to March 1963) on a swept frequency tropospheric scatter link operated at S band. The frequency transmitted is swept over a range of 200 Mc/s at a rate of 10 c/s. The receiver covers the same band in synchronisation with the transmitter. Reception is effected in space diversity by means of two antennas whose spacing is variable. Successive sweeps are received alternately on the two antennas. The results will be us d in the analysis of the effect of space diversity on transmission over a wide frequency band and its dependence on meteorological conditions. (Author)
