Abstract: An object detection method and apparatus is disclosed, where the object detection method includes determining a weather condition based on a noise floor measured in an elevated direction, and detecting an object based on comparing a signal level of a target signal measured in a depressed direction and a threshold level corresponding to the determined weather condition.

Abstract: A method of calibrating an alignment model between a first sensor that uses a radar and a second sensor that determines a position of a sensor, and an electronic device performing the method. A radar map for surroundings of the first sensor and the second sensor is generated based on the first sensor and the second sensor, and at least one object located around the first sensor and the second sensor is detected based on pre-generated data. Also, target data corresponding to the object is determined based on the radar map, an error of the target data is calculated based on a shape of the object and the target data, and the alignment model between the first sensor and the second sensor is calibrated based on the error.

Abstract: A method of determining a distance from an object performed in an apparatus including a radar, the method including receiving a reflection signal produced by a transmission signal reflecting from the object, the transmission signal being modulated by a default code sequence; converting the reflection signal into a reflection code sequence; generating a subject correlation vector including at least one correlation between at least one assistance code sequence and the reflection code sequence; and determining a distance corresponding to the subject correlation vector by referencing a lookup table storing at least one reference correlation vector including at least one correlation between the at least one assistance code sequence and the default code sequence.
