Performance of a born-approximation microwave tomographic technique under non-born conditions

A first-order Born approximation tomographic technique from far-field backscattering data, proposed and analysed elsewhere, is first introduced. The data model adopted is linear, but the reconstruction algorithm is non-linear, and its resolution power is not directly related to the working frequencies. Some simulated experimental results are then presented to evaluate the performance of the technique in the cases where the linear data model is not strictly justified.
