Abstract
In this paper, we address the problem of Through The Wall (TTW) detection with the emerging radar concept that is the multiple-input multiple-output (MIMO) radar. At first near field and through the wall propagation effects on electromagnetic waves are adressed then a MIMO frequency signal model is given and the advantages of a MIMO scheme for the complex task of TTW detection is discussed. Then image formation with beamforming processing is derived. Finally, the proposed imaging method is implemented on numerical signals obtained by FDTD computations considering through cinder blocks walls propagation. The obtained images for scenarii with one or two targets are presented.
