Abstract :
Improvements in through-the-wall radar imaging (TWRI) rely on understanding the phenomenology of the interaction between the radar signal and the wall structure. Propagation of the pulse through the wall adversely affects the resulting target return signatures through attenuation and time dispersion. One technique of improving TWRI performance is through optimal waveform design. The matched illumination concept has been shown to improve target detection and discrimination for TWRI by optimally shaping the transmission waveform to maximize the signal-to-interference and noise ratio of the radar´s transmitter-receiver pair [H. Estephan et.al, IEEE Trans. on Geoscience and Remote Sensing, Vol. 48, No. 7, pp. 2930-2941, 2010].
