On the resolution properties of a particular tomographic technique for industrial testing using ultrasounds or microwaves

In this paper the resolution properties are studied of a particular coherent tomographic technique based on the processing of the backscattered field from the body under test. It is assumed that the body itself, homogeneous and matched to the external environment, contains inside two point scatterers at distance D; with reference to this experimental condition the resolution power of the examined tomographic method are studied .in the case where microwaves or ultrasounds are used as exploring radiation. By defining a suitable Separation Factor S, maps of S are derived for va-rious D vs .. the midband frequency value and the bandwidth value used in the measure.
