The effect of the impact energy and duration on the parameters of the electromagnetic response from concrete is studied. These two parameters are shown to affect the spectral characteristics of the response. The duration of the first pulse of the response reflects the duration of the impact excitation active stage. An impact excitation energy above 5 × 10-2 J causes irreversible residual strains in concrete.
