The paper presents the XY-DemoRad - a miniature, fine-resolution FMCW (Frequency-Modulated Continuous-Wave) radar sensor capable of operating in the K-band and with a carrier frequency of 120 GHz. The radar is built around highly integrated radar modules allowing for achieving high waveform bandwidth and low power consumption. In contrast to other radar sensors utilizing such modules, the XY-DemoRad provides access to the raw radar data along with full signal processing in real time. The system is equipped with two exchangable RF (Radio Frequency) boards, allowing for selection of the operating frequency band. Technical description of the system is provided, covering the hardware, sensor's firmware and PC software. The results of system validation and performance evaluation are also featured in the text. Finally, the paper presents the sensor usability in numerous applications such as short-range surveillance with microDoppler-based target classification, drone detection, gesture recognition, detection and tracking of cars or ground-based and airborne SAR (Synthetic Aperture Radar) imaging. The paper is concluded with a summary of achieved capabilities and discussion of further development possibilities.
