US 11,378,647 B2 · Method and device for adaptively configuring threshold for object detection by means of radar

Abstract

Disclosed are a method and a device for adaptively configuring a threshold for object detection by means of radar, the device including: a position-specific maximum signal value extraction unit extracting a maximum value of a signal for each position by obtaining the signal when there is no moving object; a position-specific signal magnitude sorting unit obtaining signals caused by a moving object, and sorting magnitudes of the obtained signals for each position in descending order for a time index; a candidate signal index selection unit selecting a candidate signal index; a signal index determination unit setting weighting factors for the respective signals up to the candidate signal index, and determining a sum of the weighting factors as a signal index; and a position-specific threshold configuring unit configuring the threshold for each position by using a signal of the determined signal index and a scaling factor.
