Abstract :
Through-the-wall radar imaging (TWRI) beyond a single wall is a growing area of study. A novel near-field time-reversal match filter deconvolution procedure was proposed to improve imaging behind complex periodic walls. Promising results with improved target resolution were shown. Future work will leverage such technique to tolerate errors in wall parameters leading to an autofocus approach.
