Waveform optimization in through-the-wall imaging for ghost mitigation

The ghost clutter deteriorates target detection in through-the-wall imaging and is difficult to remove without the building structure information. In order to enhance the performance of ghost mitigation, a novel waveform optimization method is put forward in this paper to improve the signal to clutter ratio (SCR). Experiments on practical echo data further illustrate the improvement of SCR while keeping the imaging quality with the application of proposed waveform optimization.
