The invention relates to a radar device () for a motor vehicle, having a radar apparatus () for emitting and receiving electromagnetic waves () and having at least one absorption element (), which is formed from an absorption material which absorbs the electromagnetic waves (), wherein the at least one absorption element () is embodied as an element which is separate from a housing () of the radar apparatus () and is arranged outside the housing (), in particular on the housing ().

Radar device for a motor vehicle, securing device for a radar apparatus and method for manufacturing an absorption element for a radar apparatus

The invention relates to a driver assistance device () for a vehicle (), which driver assistance device has a radar appliance () for determining measured variable (&#x3b1;, &#x3b1;, R, R) referenced to an object () that is external to the vehicle, wherein the radar appliance () comprises: at least a first and a second reception antenna (), each for receiving signals (S, S); a first down-converter (), which is coupled to the first reception antenna () via a first reception path (), and a second down-converter (), which is coupled to the second reception antenna () via a second reception path (), for down-converting the received signals (S, S) into respective baseband signals (S, S); a control device () for determining the measured variable (&#x3b1;, &#x3b1;, R, R) using the baseband signals (S, S); and test means () for producing a local check signal (S) and for coupling the check signal (S) into the first reception path () and into the second reception path (), as a result of which the control device () receives the check signal (S) that has been down-converted by the first down-converter () as a first test signal (S) and the check signal (S) that has been down-converted by the second down-converter () as a second test signal (S). The control device () uses the test signals (S, S) to determine a frequency-dependent correction variable (&#x3b4;()) for correcting the measured variable (&#x3b1;, &#x3b1;, R, R). The invention also relates to an appropriate method.
