Abstract:

Three receivers forming a triangular array were located ad cent to a tra smitter operating at a frequency of 2.33 mc in Mayaguez, Puerto Rico. The signal intensity-time data were made avail-ABLE FOR ANALYSIS. Parameters related to the shape and the motion of the signal pattern on the ground were evaluated. The drift velocity of the ground pattern and a departure velocity, which is a measure of the random motions, were obtained. A total of 341 records were studied. The statistical distributions of all the data parameters are summarized. Daily and seasonal variations are considered. Spec ral analyses of the signal intensity and of the departure speeds were derived. A study of the data suggests that the signal fluctuations are essentially random and may be related to columns of ionization drifting over the receiver site. Author
