Through the wall MIMO radar detection with stepped frequency waveforms

In this paper, we present through the wall (TTW) radar detection simulations with an emerging radar architecture which is the multiple-input multiple-output (MIMO) radar. The urban environment, especially in TTW detection, is very tough for radar detection. With the aim of improving the detection performances, we use several spaced antennas in transmission which gives a spatial diversity leading to different points of view of the scene. So as to keep diversity we choose linearly independant waveforms and more particularly we utilize the hyperbolic frequency hop codes. We first begin by introduce the problems and applications of TTW detection. Then we will present the geometric configuration of the scene and the wall attenuation and target modeling. After what, we will expose the waveforms used in transmission and the processing to perform detection. We finish with some preliminary results and conclude about this work.
