摘要： A radar device is configured in such a manner that each of transmission radars uses, as the amount of phase modulation, a value determined from either one of a positive integer value that is less than or equal to a result of division obtained by dividing the number of hits of a transmission RF signal by the number of the transmission radars and a value of 0; a hit number h of the transmission RF signal; and the number of hits.

摘要： A radar sensor system is provided. The radar sensor system includes: at least two radar sensors each having at least one transmitter and at least one receiver, detection regions of the two radar sensors overlapping at least partially. The two radar sensors are situated at a defined distance from one another.

摘要： An estimation is described of the speed of objects with the aid of a radar sensor that includes multiple transmitting antennas. Multiple nested sequences of frequency ramps are emitted with the aid of multiple transmitting antennas. An individual phase encoding takes place for each transmitting antenna with the aid of a harmonic code. For estimating the speed of the object, the ambiguities due to the code multiplex are resolved.

摘要： A radar apparatus includes a transceiver and an interference wave suppression device. The transceiver outputs a transmission wave that is frequency-modulated. The transceiver receives a reflected wave propagated by reflection of the transmission wave from a target, and outputs a reception signal. The interference wave suppression device separates, when an interference wave is received together with the reflected wave, a noise signal derived from the interference wave from the reception signal and suppresses the noise signal, the interference wave being a radio wave other than the reflected wave and being frequency-modulated in a mode different from a mode of the transmission wave.

摘要： A radar system, a radar device, and an interference avoidance method are obtained that can utilize frequency effectively even in three or more radar devices. A radar system includes three or more radar devices and a schedule management controller. Schedule management controller predicts an interference time period that is a time period during which the overlapping scanning/radiation range is generated, determines a first interference avoidance measure that is a measure to cause radar devices to use respective different use frequencies while keeping a restriction on the number of frequency channels, in the predicted interference time period, and determines a second interference avoidance measure to be performed by a radar device that is unable to avoid interference by the first interference avoidance measure.
