Abstract
The invention relates to a device and a method for determining whether a living person has been buried in collapsed ground. The device consists of a rod provided with a receiver unit and a signal processing unit. The receiver unit is intended to receive reflected radar signals transmitted from a radar transmitting antenna and transfer these signals to the signal processing unit. The signal processing unit which is provided with specific detection units determines whether the received signal have been Doppler shifted. By determining that the device can decide whether the Doppler shift depends on the moving chest of a breathing person buried alive.
