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.
