Embodiment Construction

[0023] here, figure 1 A schematic illustration of a radar system 1 according to a first embodiment of the invention is shown. The radar system 1 here consists of a radar sensor head 2 which is coupled via a data line 4 to a central control unit 6 . For simplicity, radar sensor head 2 and data line 4 are shown. In this case, radar system 1 can also have a plurality of radar sensor heads 2 and a plurality of data lines 4 .

[0024] Radar sensor head 2 has, for example, a transmitting antenna 8 which can be operated via an antenna control device 10 . The antenna control device 10 is coupled to a frequency synthesizer 12 for generating a constant or variable carrier frequency of radar waves for feeding the transmitting antenna 8 .

[0025] Furthermore, radar sensor head 2 has, for example, a receiving antenna 14 for receiving radar waves, which has a corresponding evaluation unit 16 . In this case, radar sensor head 2 can have a plurality of transmit antennas 8 and / or a plural...

Abstract

A radar system for a vehicle is provided with at least one central control unit for sending data and for processing received data, at least one radar sensor head that is situated at a distance from the at least one central control unit and that has at least one transmit antenna for producing radar waves and at least one receive antenna for receiving radar waves. The radar system is provided with at least one data line between the at least one central control unit and the at least one radar sensor head, the at least one radar sensor head having an analog-digital converter for converting radar waves received by the at least one receive antenna into digital measurement data, and the external control unit having at least one analysis unit connected downstream from a data line for carrying outa processing step over at least a part of the digital measurement data.

Description

technical field [0001] The invention relates to a radar system for a vehicle having a central control unit for transmitting data and for processing received data and having at least one radar sensor head spaced apart from the central control unit, the at least A radar sensor head has at least one transmitting antenna for generating radar waves and at least one receiving antenna for receiving radar waves, and the radar system has a at least one data line for . Background technique [0002] In vehicles with high-level driver assistance functions or automated driving functions, more and more radar sensors are installed. Due to the higher number of radar sensors, a higher operating efficiency is sought in the case of automated or partially automated functions compared to individual radar sensors. Previous solutions in this field have consisted of radar sensors which carry out extensive data processing of the received radar waves within the sensor. The radar sensor can thus pr...
