Abstract: A result acquisition unit repeatedly acquires measurement results from an environment monitoring sensor that emits probe waves to a probe region and measures the distance and the direction to a reflection point at which the probe waves are reflected. A probability calculation unit calculates a detection probability for each reflection point in accordance with the measurement results acquired by the result acquisition unit. A type determination unit determines the type of the target having the reflection point in accordance with the detection probability calculated by the probability calculation unit.
