Book excerpt: From 15 February 1966 to 16 February 1967, the FCC and USAF, with the cooperation of the U. S. Coast Guard, the FAA, the U. S. Weather Bureau, and NASA, conducted an investigation known as the POPSI (Precipitation and Off-Path Scattered Interference) Project. The investigation involved studies of the scattered signal from precipitation and other mechanisms located in the common volumes established by the intersections of the beams from a transmitting antenna operating in a configuration simulating a satellite earth station, and receiving antennas configured in a manner typical of terrestrial microwave radio relay stations. The project was designed to obtain data at a frequency of 5.75 GHz for a statistical treatment to estimate the magnitude of the problem of both on and off-path scattered interference between microwave radio relay stations and satellite system earth stations sharing the same frequency bands. More than 3000 hours of field strength measurements were recorded. Some attempt has been made to correlate the enhanced fields with meteorological phenomena, although the mechanisms have not been examined in great detail for this report. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The electromagnetic field strength measurements obtained during the 1966 FCC/USAF POPSI Project have been classified according to propagation mode and the data from periods of precipitation have been analyzed in detail. Cumulative probability distributions were generated for the effective radar reflectivities derived from the bistatic electromagnetic measurements and compared with the probability distributions of the surface rainfall rates derived from the accumulations of the United States Weather Bureau recording rain gauges in the area. The distribution functions were then adjusted by means of a least squares regression line. The relationship thus obtained has been compared with other Z-R relationships based upon the analysis of drop size distributions and has been tested against independent rain gauge data in the POPSI Project area. The final approximation resulted in a standard deviation for estimating Z(p) from R(p) of less than 1.6 dB for the New Jersey rainfall data. The altitude dependence of the reflectivity from precipitation-connected phenomena in the New Jersey coastal area has been demonstrated and discussed to some extent. (Author).
