Abstract
A method for monitoring the performance range of a radar system placed behind a portion of a vehicle including, in an operational mode, the steps of: transmitting a first signal in a high range resolution mode from the radar system through the portion of the vehicle; receiving a first return signal comprising a part of the first signal that is reflected by the portion of the vehicle at the radar system; measuring the first return signal; comparing the first return signal with a calibration return signal representative of a part of the first signal that is reflected by the portion of the vehicle in a calibration mode; determining the relative loss of transmission of the portion of the vehicle from the comparing step.

A method for monitoring the performance range of a radar system placed behind a portion of a vehicle comprising, in an operational mode, the steps of:
- transmitting a first signal in a high range resolution mode from the radar system through the portion of the vehicle;
- receiving a first return signal comprising a part of the first signal that is reflected by the portion of the vehicle at the radar system;
- measuring the first return signal;
- comparing the first return signal with a calibration return signal representative of a part of the first signal that is reflected by the portion of the vehicle in a calibration mode;
- determining the relative loss of transmission of the portion of the vehicle from the comparing step.
A radar system placed behind a portion of a vehicle and configured to detect an object in the outside environment of the vehicle, comprising:
- an antenna configured to detect a reflected signal characterized as a reflection of an emitted signal reflected by the object present in a field-of-view of the antenna;
- a controller configured to:
- transmit a first signal in a high range resolution mode from the radar system through the portion of the vehicle;
- receive a first return signal comprising a part of the first signal that is reflected by the portion of the vehicle at the radar system;
- measure the first return signal;
- compare the first return signal with a calibration return signal representative of a part of the first signal that is reflected by the portion of the vehicle in a calibration mode;
- determine the relative loss of transmission of the portion of the vehicle.
