“…Hence, we have to calculate the scattering matrix of the lap joint geometry to compare the CFIE approach to a measurement. The different elements of the simulated scattering matrix [12] can be derived by using the reciprocity theorem at the center frequency of the radar system. To calculate the matrix entries S kl ( u x ), the antennas act as transmitter and/or receiver.…”

In this paper, we present the results of using a frequency-stepped continuous-wave radar system to estimate the position of overlapping and electrically good conductive plates. We especially focus on polarimetric scattering effects caused by the step of a lap joint, which is a common welding-geometry. To model the step's contribution to the overall scattered signal, we use a two-dimensional combined field integral equation (CFIE) approach. For demonstrating its practical applicability, the implemented scattering model is verified by measurements. To emphasize the improvements of position estimation by using a CFIE approach, the outcomes of the model are compared to a commonly used point scattering model. Finally, the numerical signal is utilized to precisely estimate the position of the lap joint.
