Abstract: A detector (210) for indicating bodily functions of a person in the surroundings of the detector (210) is proposed. The detector (210) comprises a support structure and a Continuous-Wave (CW) radar module (214) supported by the support structure. The radar module (214) is configured to emit microwaves and receive microwaves that have been reflected in the surroundings of the detector (210), wherein the radar module (214) is configured to determine data indicating bodily functions from microwaves reflected on a person. The detector (210) further comprises a collimator (216) supported by the support structure and configured for collimating the emitted microwaves in one spatial direction, or towards a plane.

Abstract: A method, an antenna, and a system for determining positions for reflection points using microwaves. An electromagnetic wave signal is generated at a defined frequency, and transmitted by an antenna unit the antenna unit includes a transmitter antenna and a plurality of receiver antennas, separated by a known spacing perpendicular to a main line of sight and devised to receive reflected portions of the transmitted wave. Phase comparator means are connected to the transmitter antenna and the receiver antennas, and a control unit connected to the phase comparator means is operable to calculate an angle to a reflection point from detected phase difference between at least two receiver antennas and the spacing between said at least two receiver antennas, and to calculate a distance to the reflection point from detected phase difference between the transmitter antenna and a receiver antenna dependent on the frequency.
