Abstract
It is suggested to process radar signals including (i) determining a variation of at least one radar parameter provided from at least one radar device; (ii) determining an estimated value of at least one radar parameter from an error compensation vector; and (iii) determining a safety condition based on the variation and the estimated value for the respective radar parameter.
Claims13
A radar device configured to process radar signals, comprising:
- a signal processing circuit configured to receive radar signals and perform processing thereon to form a digitized antenna data set;
- one or more fast fourier transform (FFT) processor circuits configured to receive and process the digitized antenna data set and output interim results that comprise a portion of processed received radar signals that signifies a peak or peak structure indicative of one or more detected objects;
- an electronic control circuit configured to receive the interim results and generate an error compensation vector based on a comparison of the interim results and one or more ideal radar characteristics;
- wherein the electronic control circuit is further configured to:
- receive a radar parameter from the signal processing circuit or other external device and calculate a variation between the radar parameter and a corresponding radar parameter from a specification or other corresponding predetermined radar parameter;
- determine an estimated value of the radar parameter from the generated error compensation vector, wherein the estimated value corresponds to a radar parameter value that would result in the error compensation vector;
- determine a safety condition based on a comparison of the calculated variation and the determined estimated value for the respective radar parameter;
- and
- selectively apply the generated error compensation vector to the interim results based on the determined safety condition.
