Centimeter and millimeter-wave radio signals attenuation in explosions

The mechanisms of centimetre and millimetre radio wave attenuation in the explosion area of chemical explosives are analyzed. It is shown that the dominant factor is the attenuation caused by absorption in finely dispersed solid explosion products. The results of experimental measurement of the attenuation factor, the area dimensions important for attenuation and the duration of its existence for wavelengths of 0.4, 0.8, 3 cm are presented. A comparison of experimental data with results of derivations is performed.
