Abstract
A radar sensor comprises a radar transmit and receive unit configured to transmit radar waves to an external environment of the vehicle and to receive radar waves from the external environment of the vehicle, and an interface unit attached to the radar transmit and receive unit. One or more design and/or material parameters of the interface unit are adjusted to fit a predetermined installation position at the vehicle with respect to desired characteristics of the transmitted and received radar waves. A corresponding method for integrating a radar sensor in a vehicle is also disclosed.
Claims13
A radar sensor for a vehicle, comprising:
- a radar transmit and receive unit configured to transmit radar waves to an external environment of the vehicle and to receive radar waves from the external environment of the vehicle, and
- an interface unit attached to the radar transmit and receive unit, wherein one or more design and/or material parameters of the interface unit are adjusted to fit a predetermined installation position at the vehicle with respect to desired characteristics of the transmitted and received radar waves
- wherein the one or more design and/or material parameters of the interface unit are configured to provide a desired radiation pattern for the transmitted and received radar waves, the interface unit replaces a radome, and an outer surface of the interface unit is adjusted to an outer surface of the vehicle.
A computer implemented method for integrating a radar sensor in a vehicle,
- wherein the radar sensor includes a radar transmit and receive unit configured to transmit radar waves to an external environment of the vehicle and to receive radar waves from the external environment of the vehicle, and an interface unit being attached to the radar transmit and receive unit, the method comprising:
- determining a desired installation position of the radar sensor at the vehicle, and
- adjusting one or more design and/or material parameters of the interface unit to the desired installation position with respect to desired characteristics of the transmitted and received radar waves,
- wherein determining the desired installation position of the radar sensor includes:
- receiving data associated with a geometrical shape of the vehicle,
- simulating the transmitted radar waves for a plurality of candidate positions at the vehicle based on the received data, and
- selecting one of the candidate positions as the desired installation position for which a deviation between a radiation pattern of the simulated transmitted radar waves and a desired radiation pattern is minimized.
