Abstract
The invention relates to a Doppler radar heart sensor comprising a radar signal emitter (); a radar signal receiver (); a signal pattern matcher (); and a transmission power adjuster (). The signal pattern matcher () is connected to the radar signal receiver () and arranged to analyze a received radar signal (), to compare the received radar signal with signal patterns, and to issue a corresponding indication signal upon detection of a sufficiently high similarity between the received radar signal and at least one of the signal patterns. A transmission power adjuster () is connected to the radar signal emitter () and the signal pattern matcher (), the transmission power adjuster being arranged to gradually modify a transmission power delivered to the radar signal emitter () until the signal pattern matcher issues the indication signal. The invention also relates to a corresponding method and a computer program product.
