In the modelling of electromagnetic scattering in a Through-the-Wall environment large domains made by walls, and sparse targets are involved. Approximated models based on ray-tracing techniques are mostly employed to reduce computer times, although a more accurate response that takes account of all the interactions between walls and targets may be obtained with full-wave methods. In this work, the Cylindrical Wave Approach is employed, as full-wave technique for the modelling of Through-the-wall scenarios. The technique is mainly analytical, as targets with circular cross-section are modelled through expansions into cylindrical waves. However, through suitable rules, it is possible to approximate targets with cross-section of arbitrary shape through an arrangement of smaller circular cross-section cylinders. This may be applied, for example, to the modelling of pieces of furniture, as wall as to introduce further walls in the simulation domain.
