Abstract: A transceiver unit, particularly for measuring applications, comprising a transmitter (1) for generating a signal, an acquisition antenna (5) for emitting the signal in an acquisition volume and for picking up an effective echo signal reflected by the acquisition volume, as well as a receiver (2) for evaluating an echo signal supplied by the acquisition antenna (5). The echo signal is composed of the effective echo signal and an unwanted echo signal generated by the acquisition antenna (5). In order to compensate for the unwanted echo signal, an antenna simulation (6) is connected via a coupler (3) to the transmitter (1) and the receiver (2) which, after having received the signal, supply an correction signal in proportion to the unwanted echo signal. The coupler so heterodynes the correction signal and the echo signal that the correction signal and the unwanted echo signal cancel out each other.

Abstract: The invention relates to a connection piece (20), comprising an upper connection piece part (21) and a connection piece wall (22) disposed below said upper connection piece part (21) and having a connection piece wall height (h). In said upper connection piece part (21), a level metering device (10) working on the guided microwave principle and comprising a single electric line (40) can be mounted. Connection piece (20) further comprises at least one electrical conductor (30a, 30b, 30c, 30d, 30e, 30f) spaced apart at a distance (a, a′) from the single electric line (40) of the level metering device (10) to be mounted on the upper connection piece part (21) and extending from the upper connection piece part (21) up to at least the 0.25-fold, and maximally up to the 2.5-fold of the connection piece wall height (h).

Abstract: The present invention pertains to a method for range measurement by means of a signal transmitted in the direction of an object to be measured, wherein an echo signal, on which is superimposed a first reference pulse, is received by a receive device, wherein the echo signal is compared with a second reference signal that features a second reference pulse for determining a signal travel time, and wherein a first comparison value of the echo signal and a second comparison value of the second reference signal are compared with each other for determining an amplitude offset between the echo signal and the second reference signal, and these values, in regards to time, are before the first and second reference pulses in a region of the echo signal curve and of the second reference signal curve, respectively, and in these regions, these curves feature a slope that is at least approximately zero.

Abstract: A transceiver unit, particularly for measuring applications, comprising a transmitter (1) for generating a sampled signal, an acquisition antenna (5) for emitting the sampled signal in an acquisition volume and for picking up an effective echo signal reflected by the acquisition volume, as well as a receiver (2) for evaluating an echo signal supplied by the acquisition antenna (5). The echo signal is composed of the effective echo signal and an unwanted echo signal generated by the acquisition antenna (5). In order to compensate for the unwanted echo signal, an antenna simulation (6) is connected via a coupler (3) to the transmitter (1) and the receiver (2) which, after having received the sample signal, supply an unwanted echo signal in proportion to the correction signal. The coupler so heterodynes the correction signal and the echo signal that the correction signal and the unwanted echo signal delete each other.
