摘要： A fill level radar device including a transmission-power adjustment apparatus which is configured to adjust the power of the transmission signal depending on the frequency of the transmission signal in accordance with a predefinable correlation. As a result, frequency-dependent absorption changes in the filling material atmosphere can be compensated for by the device.

摘要： A reflection microwave barrier for monitoring a limit level in at least one working area by outputting a switching signal. The reflection microwave barrier including a microwave transmitter for continuously emitting a time modulated microwave signal, a microwave receiver arranged on the same side of the at least one working area as the microwave transmitter to receive a reflection of the microwave signal, and a control circuitry communicating with the microwave receiver for a detection and monitoring of echo signals in the received reflection of the microwave signal. The control circuitry calculates the runtime of an echo signal), when the amplitude of the echo signal rises or increases. Furthermore, the control circuitry determines by the calculated runtime, whether an origin of the echo signal lies within the at least one working area, and only outputs the switching signal in this case.

摘要： A FMCW fill level sensor comprising an equaliser that equalizes the intermediate frequency signal digitalised by an analogue-digital converter. Equalising is carried out, for example, in the form of convoluting the digitalised intermediate frequency signal by an equalising function in the time domain. It is also possible to equalise the digitalised intermediate frequency signal by multiplying the signal by an equalising function in the form of a transfer function G(ωk) to form the discrete frequency in the frequency domain. A digital filter can also be used. This can increase the accuracy with which the fill level is determined.

摘要： A FMCW fill level radar device including a control circuit for temporarily shifting, during the measuring phase, one component of the transceiver circuit into a state having reduced power consumption, resulting in the measurement being interrupted. This results in the total power consumption of the fill level radar device being reduced such that energy can be accumulated in the device, after which the measuring phase is continued.
