Abstract
An apparatus for detecting diffuse reflection noise with respect to ultrasonic sensor values is disclosed. The apparatus includes a plurality of ultrasonic sensors; and a processor including a diffuse reflection noise detector for detecting diffuse reflection noise in sensor values obtained from the ultrasonic sensors. The diffuse reflection noise detector is configured to detect single-sensor-based diffuse reflection noise in obtained sensor data, and is configured to detect multi-sensor-based diffuse reflection noise when the single-sensor-based diffuse reflection noise is not detected.
