Abstract :
A short-distance FMCW radar system is described which has been used to detect the presence of objects embedded in brick walls. Digital signal processing and microprocessor control are used to enhance the detection sensitivity by a subtraction process. The system has detected small air-filled cavities and metal rods in brick walls.
