A large number of microwave sensors are available on the market today. Unfortunately, sensors of high quality are very expensive and tend to be stationary, making them unsuitable for integrating into an industrial process. Processing of microwave data is a challenging and complex task, and leads to high computational demands and increased processing time, so real-time quality control becomes virtually impossible. In this paper, we introduce a prototype system for nondestructive testing that utilizes moderately expensive continuous wave (CW) sensors. We exploit the physical phenomenon of the Doppler Effect to detect discontinuities in materials. We also propose an approach for fast measurements and data processing.
