摘要： The invention relates to an ultrasonic anemometer (7) and a method for determining at least one component of a wind speed vector and/or a sound speed with at least one sound transducer (1, 2, 3, 4, 5, 6, 15, 16) working at least intermittently as a transmitter and having a sound emission surface for emitting sound waves, and with at least one sound transducer (1, 2, 3, 4, 5, 6, 15, 16) working at least intermittently as a receiver and having a sound detection surface for at least partially receiving the emitted sound waves, and with an evaluation unit which determines at least one component of a wind speed vector and/or the sound speed on the basis of a detected duration which is required by the sound waves to be in a measurement section between the sound emission surface of the at least one transmitter and the sound detection surface of the at least one receiver in order to cover said measurement section. The technical solution according to the invention is characterised in that at least one first measurement section is arranged approximately vertical to the ground surface between a first sound emission surface of a first transmitter and a first sound detection surface of a first receiver, and in that the first sound emission surface and/or the first sound detection surface are inclined in relation to the horizontal.

摘要： The invention relates to a device and a method for measuring a change in distance between a stationary initial point and an object, wherein frequency-modulated, continuous electromagnetic microwaves are emitted as an emitting signal (4) in the direction of the object such that the emitting signal (4) is reflected by the object and an echo signal (5) that is generated at the object following the reflection of the emitting signal (4) is received and evaluated. The method according to the invention or the FMCW radar apparatus designed according to the invention is based on a hardware extension of a standard FMCW radar apparatus and offers the possibility of evaluating a time-independent part of the mixed signal phase (6) by means of an evaluation electronics (18) while taking into account a propagation time of the emitting (4) and/or echo signal (5) between emitting unit (2) and object so that a change in distance between emitting unit (2) and object can be detected as a result of a change in propagation time.

摘要： The invention relates to a receiving device for a radar device, especially in continuous wave mode, especially for radioacoustic sounding systems (RASS). The receiving device comprises a receiving antenna (35) and a mixing device (50) for mixing a useful signal (80) with another signal. The invention is characterised in that the other signal is exclusively an interference signal (90) which creates crosstalk in the receiving device (90).
