Abstract

Frequency modulated continuous wave (FMCW) radar is moving from long range detection to indoor short distance target monitoring and has already demonstrated its unique advantages over other approaches. The state-of-the-art coherent FMCW radar, especially, can provide very accurate result in small motion signal detection. However, the performance is sensitive to the clutters that surround the target. In this paper, a clutter reduction technique is developed to further enhance the performance and the robustness of coherent FMCW radar for physiological signal detection. Both theoretical and experimental results are presented to demonstrate the feasibility of the adopted solution.
