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...

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.
