摘要： Methods and apparatuses pertaining to radar interference mitigation are described. A processor associated with an apparatus may generate a plurality of wave frames such that one or more aspects of the plurality of wave frames vary from one wave frame to another wave frame of the plurality of wave frames. Each of the plurality of wave frames may respectively include a plurality of chirps. A wireless transmitter associated with the apparatus may transmit the plurality of wave frames. A wireless receiver associated with the apparatus may receive one or more reflected waves comprising at least a portion of one or more of the wave frames reflected by an object. The processor may determine a distance between the object and the apparatus, a speed of the objet, or both, based on an analysis of the one or more reflected waves.

摘要： An object detection method includes: obtaining a first offset value and a second offset value, setting a first detection threshold value by adding the first offset value to a first reference threshold value, setting a second detection threshold value by adding the second offset value to a second reference threshold value, obtaining a detection input, and performing target detection upon the detection input according to at least the first detection threshold value and the second detection threshold value. The first offset value is different from the second offset value. The first reference threshold value is determined for detecting if at least one object with a first value of an object characteristic exists. The second reference threshold value is determined for detecting if at least one object with a second value of the object characteristic exists. The second value is different from the first value.
