SWEEP-FREQUENCY BACKSCATTER WITH CALIBRATED AMPLITUDE

Abstract

The purpose of this work was the compilation of representative sets of experimental records of sweep-frequency ground backscatter--quantitative in amplitude, frequency, and group time delay. These data are intended to serve as a comprehensive source of high quality experimental data for theoretical backscatter studies currently in progress. The invention of computer techniques for the study of ionospherically propagated ground backscatter has opened new avenues for productive research. However, efforts to exploit the computer synthesis have been hampered by the apparent lack of published, adequately- calibrated backscatter records. To gather these needed data, a special, highly instrumented and calibrated backscatter radar was assembled and operated for many months. The result is a large quantity of experimental information that should be of general use to the scientific community in the study of backscatter.
