Embodiment Construction

[0029] figure 1 A schematic illustration of the proposed radar sensor head 100 is shown. Radar sensor head 100 has at least one transmitting antenna 10 which can be operated via an associated antenna control device 11 . The antenna control device 11 is also coupled to at least one oscillator or synthesizer 30 for generating the carrier frequency of the radar waves.

[0030] Furthermore, at least one receiving antenna 20 is connected to an associated antenna control device 21 . Antenna control device 21 is functionally connected to evaluation unit 40 , wherein the received radar waves are converted into digital measurement data by means of an analog-to-digital converter arranged in evaluation unit 40 and subsequently in a first processing step by means of The preprocessing unit 50 transforms.

[0031] The radar waves received by the receiving antenna 20 of the radar sensor head 100 may be converted into digital measurement data by an analog-to-digital converter and may be ma...

Abstract

Radar sensor head (100) for a radar system, having: at least one transmitting antenna (10) for generating radar waves and at least one receiving antenna (20) for receiving radar waves; a preprocessingunit (50) for preprocessing received data in a defined manner; an interface (80) for connecting the radar sensor head (100) to a data line (110); and a calibration data device (50, 70) for at least partially calibrating the transmitting antenna (10) and / or the receiving antenna (20), wherein calibration data for the transmitting antenna (10) and the receiving antenna (20) can be stored by means of the calibration data device (50, 70).

Description

technical field [0001] The invention relates to a radar sensor head for a radar system. The invention also relates to a radar system. The invention also relates to a method for producing a radar sensor head for a radar system. Background technique [0002] An increasing number of radar sensors are installed in vehicles with high levels of driver assistance functions or autonomous driving functions. Due to the greater number of radar sensors, a higher operating efficiency of automated or partially automated driving functions is aimed at compared to a single radar sensor. Previous solutions in this field consisted of radar sensors which carried out a sensor-internal large-scale data processing of the received radar waves. Radar sensors can thus provide data at the object or location level for further evaluation by the vehicle. As a result, the amount of data transmitted to the vehicle can be reduced, but the corresponding radar sensor must have a high computing power and a...
