Featured points method of amplitude recovery

Abstract

A method for ground-penetrating radar amplitude recovery of targets is presented in this paper. We use the migration processing for target imaging and the clean method to extract featured target points.Based on the featured target points, target reflection hyperbolas are calculated. Curve fitting is applied to get amplitude attenuation parameters. The amplitude is recovered after compensating the parameters to the raw data. We performed a field experiment with 5 sphere targets under water. Comparing to the conventional methods, our proposed method is more effective for target classification.
