Stationary clutter can seriously degrade the performance of radar sensors. In specific context vital‐sign monitoring, this deterioration lead to impossibility tracking desired motions. Pure linear‐frequency‐modulated continuous‐wave (LFMCW) radars have arisen as an interesting solution monitor vital signs, featuring both increased phase‐based range precision and advantageous range‐isolation capability. study, impact on healthcare LFMCW is mathematically analysed a Doppler high‐pass filtering technique proposed for its suppression. Simulation results are provided highlight key aspects derived mathematical framework associated processing. Real experiments also conducted prove validity devised clutter‐mitigation procedure.
