The detection of eyeblinks serves as one of crucial human indices for evaluating physiological and psychological states in diverse applications. This research is focused on the use of Frequency Modulated Continuous-Wave (FMCW) radar technology for monitoring eye blinks, with a comprehensive investigation of eyeblink detection methods and the impact of blink interval, change of gaze, head movements, wearing glasses, and presence of nearby people. In contrast to previous studies, which often overlooked these factors, our research aims to comprehensively understand their influence. Subsequently, a method is proposed based on derivatives and high-pass filters to accurately detect eye blinks while minimizing the influence of simultaneous eye and head movements. The evaluation of the proposed method has demonstrated impressive performance, yielding an overall F1-score of 97.8% within distances ranging from 40 to 100cm. Furthermore, the results indicate the methods capability to detect eye blinks at distances up to 250cm, achieving an F1-score of 83.1%. These findings underscore the effectiveness of our approach in overcoming the challenges posed by various eye and weak head movements.
