Recent developments both in measurement techniques and reconstruction algorithms have shown the possibility of quasi-real time microwave tomography. These technical developments always require more sophisticated experimental arrangements in order to reduce the microwave circuits complexity, decrease the measurement time, and improve the resolution. This paper deals with the use of crossed linear arrays convenient for tomography by transmission. Numerical simulations and initial experimental results show the relative advantages of such arrangements as compared to the more classical two-dimensional arrays.
