Radar sensor having a mixer for mixing a received signal with a reference signal and having a device for compensating interference signals which would overload the mixer, wherein the device for compensating the interference signals has an adjustable reflection point at the reference input of the mixer.

Radar sensor having interference signal compensation

In a multibeam radar sensor apparatus having at least two transmission/reception channels, whose signal paths each include an antenna and a mixer, at least one first mixer is configured bidirectionally as a transfer mixer, and at least one second mixer is switchable from a first into a second operating state; in the first operating state, the mixer is bidirectionally configured as a transfer mixer, and in the second operating state, the mixer being configured in an at least approximately isolating manner as a receiving mixer. In addition, in a method for determining a distance and/or a speed of a target, a radar signal is transmitted in a direction of the target and a reflected radar echo is received, for which at least two transmission/reception channels are used whose signal paths each include an antenna and a mixer; at least one mixture is switched over from a first into a second operating state, in order to use the mixer, in the first operating state, bidirectionally as a transfer mixture, and, in the second operating state, in an at least approximately isolating manner as a receiving mixer.

Multibeam radar sensor apparatus and method for determining a distance

A radar sensor having a transmission module and a signal stabilizer, which are situated on a shared circuit board, a casing, which accommodates the signal stabilizer and forms a shield against high frequency radiation of the signal stabilizer together with a conductive layer of the circuit board, and having a connection line, which crosses through the shield, to connect the signal stabilizer to the transmission module, in which the connection line is embedded in the circuit board in insulated fashion.

Radar sensor having a shielded signal stabilizer

A device for transmitting and receiving electromagnetic radiation includes separate antennas for transmitting and for receiving electromagnetic radiation and in which the lobes of the transmitting and receiving antennas are focused by a shared focusing arrangement.

Device for emitting and receiving electromagnetic radiation

A radar sensor emits microwave radiation and receives partial radiation reflected at objects within the sensor detection range, a plurality of antennas being provided for the transmission and reception in each case, and the transmission power of the outer antennas being lower than the transmission power of the inner antennas. This is accomplished by reducing the transmission power with the aid of couplers, the couplers advantageously being implementable as Wilkinson power splitters.

Radar sensor

A microwave oscillator having a hollow conductor, an oscillation generator which is mounted on a heatsink and projects into the hollow conductor, and a printed circuit board having electronic components for supplying direct voltage to the oscillation generator. The printed circuit board or a metallic coating on, in, or under this printed circuit board forms one wall of the hollow conductor, and the oscillator including its heatsink is located in the printed circuit board.

Microwave oscillator

An arrangement for frequency-selective suppression of high frequency signals is described, with a hollow chamber (,) including at least partially electrically conductive walls (,) and having radiator elements (,), embodied by stripline technology, for coupling the high frequency signals into and out of the hollow chamber (,). At least two radiator elements are present, of which at least one is intended for coupling in the high frequency signals and at least one other is intended for outcoupling them. The at least two radiator elements (,) are embodied on separate substrate faces (,). The separate substrate faces (,) are disposed on a common substrate plate (,), and the hollow chamber is formed by a hood (,), which is disposed on or above the substrate plate (,) in such a way that it covers the radiator elements (,). It is especially advantageous if the hood (,) is integrated with the housing wall (,) of a shielding housing.
