摘要：
A K-band radar system for detecting and monitoring cardiorespiratory signals of a human being is presented. The proposed radar system can be used in hospitals or homes to monitor the vital conditions of patients or elder people. If there is an abnormality, the radar system is capable of sending an alert signal to the remotely located monitoring terminal via the internet. In this work, the settling time of the analog baseband signal is optimized. To increase the dynamic range of the K-band radar, an automatic gain control unit is successfully designed and implemented. Also, to avoid null points in measurements, both in-phase and quadrature signals are used in processing.
