Contents I. Introduction
Waveform shaping has been used by researchers for mitigating clutter and noise in radar systems and has been recently applied to TWRI [1]–[6]. TWRI is an important technology used for surveillance and reconnaissance in both military and civil applications; however, detection and identification of targets located behind walls is a challenging problem due to the attenuation and dispersive effects of the wall. As the transmission pulse propagates through the wall, the target return signature is obscured; thus, an optimal transmission pulse which accounts for the wall is need for more successful target classification and discrimination.
