Attenuation characteristics of microwave pulse penetrating walls

The characteristics of microwave pulses from different sources penetrating various kind of walls were studied. The walls used in the experiment included common brick-mix wall, common reinforced concrete wall and reinforcing steel bar-net concrete wall. The microwave sources used were narrow band microwave source, 100 V UWB radiation source and single periodic UWB pulse radiation source. The attenuation and the change of spectrum for different electromagnetic pulse after penetrating various walls were provided and analyzed. For the narrow band pulse penetrating common brick-mix wall and common reinforced concrete wall, the attenuation was 0.342～0.699 dB/cm. For the UWB pulse penetrating common brick-mix wall and common reinforced concrete wall, the attenuation was 0.134～0.183 dB/cm. For r
