Tropospheric Scatter Propagation Measurements Beyond the Horizon in Arid Zone-A Note

Tropospheric scatter study beyond the horizon radio link presently necessitates tests to establish the median path loss and to determine the magnitude and duration of the path loss variations. The average basic transmission loss of the scattered component, Lbs can be found if K (ratio of r.m.s. value of scattered and constant component) and the resultant basic transmission loss Lbm are known. This paper also deals with the diurnal and seasonal behaviour of signal strength, based on the ana!ysis of about ten months recording on a C band Troposcatter Link between Pilani and Delhi
