A PRELIMINARY LOOK AT BACKSCATTER OBSERVATIONS ALONG A HIGH LATITUDE RADIO PATH

Statistics of the backscatter echoes observed by an HF pulse radar for nearly 24 months are presented. The data were gathered at a joint (monostatic) transmitting and receiving site located near Washington D.C., along a transmission path which passed near to the geographic north pole and which can b...

Description
Summary:Statistics of the backscatter echoes observed by an HF pulse radar for nearly 24 months are presented. The data were gathered at a joint (monostatic) transmitting and receiving site located near Washington D.C., along a transmission path which passed near to the geographic north pole and which can be best described as a transauroral path. The observations were made from February 1959 to March 1961 during which time the average smoothed sunspot number decreased from 150 to less than 70. Conclusions regarding the effects of the geophysical environment on the observed data and the intercomparison of various other propagation evaluation techniques with that of ground backscatter are given.
