Radar sensor system for blood pressure sensing, and associated method

In an embodiment, a method includes: generating a displacement signal indicative of a distension of a surface of a skin; determining a temperature of the skin using a temperature sensor; during a calibration time interval, collecting a plurality of distension values from the displacement signal, the plurality of distension values associated with a respective plurality of temperature values determined using the temperature sensor, the plurality of temperature values being indicative of a temperature change of the skin; determining compensation coefficients associated with the plurality of temperature values; and after the calibration time interval, collecting a first distension value from the displacement signal, determining a first temperature value using the temperature sensor, and determining a blood pressure based on the first distension value, the first temperature value, and the determined compensation coefficients.
