The examination of concrete walls is an important schedule in civil engineering. For these opaque and uncontinuous object, microwave technique is an effective method to realize nondestructive testing (NDT). A series of data coming from different frequencies and positions can be used to reconstruct an image of the section of the concrete wall. The equipment for microwave NDT is a small-size radar,...
