A method for low-interference operation of a plurality of radar sensors, which are installed in different vehicles and each emit a transmission signal in an operating range, which is characterized by at least one of the following parameters: frequency, coding, activity time window. Each radar sensor is assigned an operating range according to at least one degree of freedom of movement of the vehicle, in which the radar sensor is installed.

Method for low-interference operation of a plurality of radar sensors

A waveguide system for a transition between a waveguide structure having an exterior stripline element and a waveguide structure having a stripline element which is completely shielded. To that end, the present invention provides a transition which is able to be realized particularly easily and efficiently with the aid of a multilayer printed circuit board architecture.

Waveguide system, high-frequency line and radar sensor

A radar system including a reference channel formed symmetrically in relation to a main channel, with a first oscillator, generating a first input signal, which is feedable to an antenna in the main channel, a reflected portion of the first input signal being feedable to a first mixer, the first input signal in the reference channel being feedable to a second mixer via a second directional coupler, with a second oscillator, generating a second input signal having a frequency differing from the first input signal in a defined way, which is feedable to the first and second mixers, the signal coming from the mixer of the main channel and the signal coming from the mixer of the reference channel being compared, and dimensioning a terminating impedance of the reference channel as a function of the comparison so that the output signals of the main and reference channels have identical properties.

Method for calibrating a radar system

An antenna device for receiving electromagnetic waves and a method for operating an antenna device. The antenna device is fashioned having: a bearer; at least one receive antenna device situated at an external side of the bearer, for receiving electromagnetic waves having a first polarization; at least one repolarization device situated at the external side of the bearer and fashioned to re-emit electromagnetic waves impinging on the repolarization device having the first polarization as electromagnetic waves having a second polarization; and a filter device situated at the external side of the bearer and fashioned to absorb electromagnetic waves having the second polarization.

A determining device for determining at least one component of a liquid, e.g., a fuel mixture, for use in motor vehicles, includes at least one sensor which has at least one connecting device for coupling microwave signals into the liquid and/or out of the liquid. The determining device is implemented as a hand-held measuring instrument.

Device for determining a composition of a liquid

A device for determining a composition of a fuel mixture is provided, in particular for determining an ethanol component and/or a water component in the fuel mixture. The device includes at least one housing having at least one electrically conductive housing element through which the fuel mixture is able to flow. At least one internal conductor, which is at least partially enclosed by the housing element, is introduced into the housing element. In addition, the device has at least one connection device for the coupling of microwave signals.
