In 1968 a joint study of radar-auroral backscatter was carried out by Bell Laboratories, Western Electric, and Lincoln Laboratory using the 448-MHz radar of the Prince Albert Radar Laboratory. They made observations covering a range of magnetic aspect angles from 4.5¿ to 16¿, but the results were not published in the open literature. These data have been reanalyzed and used to obtain results on the aspect sensitivity, flow angle dependence, absolute scattering cross section, Doppler velocity distributions, and the azimuthal variation of Doppler velocity for large aspect angle auroral backscatter. The average aspect sensitivity was found to be independent of aspect angle and to decrease with increasing backscatter power. Estimates of the largest absolute scattering cross sections were much greater than previous estimates at the same aspect angles, but these cross sections appear to be consistent with previous values once the long duration of the experiment is taken into account. Backscatter power was found to be essentially independent of flow angle. ¿ American Geophysical Union 1996
