PROBLEM TO BE SOLVED: To provide an apparatus and a method for detecting a mobile unit allowing to detect a mobile unit stably, even under the condition where the environment in the monitoring area fluctuates and the condition where the reference plane for detecting the mobile unit cannot be set to be a plane. SOLUTION: A background distance generation section 21, on the basis of measurement results of a laser radar 10, generates a background distance map, indicating the distance information from the laser radar 10 in a detection area to an object in the background. A mobile unit detecting section 23 detects a mobile unit in the detection area from the difference between the distance information of the background distance map stored in a background distance map memory 22, in advance, and the measurement results of the laser radar 10.
