Abstract
Ghost Object Identification For Automobile Radar Tracking A method of classifying an object detected by a radar device (R) includes identifying two dynamic objects (O) and one stationary object from sensor data detected by at least one sensor; determining a plurality of confidences based on a comparison of the separation distance between each object and a range of each object to the sensor. The method also determining a highest confidence value among them; comparing the highest confidence to a p re-defined threshold; and increasing a corresponding ghost probability, when the highest confidence value is higher than a predetermined threshold or decreasing the corresponding ghost probability, when the highest confidence value is not higher than the predetermined threshold. The method also includes marking the object as a ghost object when a probability of a less confident object is higher than an upper threshold and setting a ghost probability to zero when the less confident object is lower than a lower threshold.
