This paper proposes that the statistical property of the wave form obtained by a pulse type subsurface radar follows the Weibull probability density distribution. The shape parameter of this distribution is related to the underground condition. By using the shape parameter, we calculated the statistical variance. The ratio of the variance of target area to that of non-target area in invisible medium is evaluated for the effect of the radar signal processing. Over 20dB improvement, for example, can be obtained by means of Log/CFAR processing. It made clear that the cell size of processing should be selected the length corresponding to self-correlation.
