Abstract :
UWB radar system facilitates us to estimate positions and shapes of objects behind the wall. We have made real through the wall SAR measurements with bistatic M-sequence UWB radar system. A metal plate, an aquarium filled with water and a wooden cupboard inside the room with concrete wall have been scanned. The simple and fast algorithm for compensation of different wave velocity inside the wall is described. Measured data are processed with 2-dimensional geometrical based SAR migration in time domain. Conductive materials behind the wall scanned with M-sequence UWB radar system are clearly visible.
