Abstract
An object sensing apparatusincludes: an emission unitconfigured to emit an RF transmission signal as an electromagnetic wave for object sensing; a reception unitconfigured to receive a reflected wave of the RF transmission signal as an RF reception signal, and use the RF transmission signal to generate a demodulated signal based on the RF reception signal; a distance detection unitconfigured to detect a distance to the object that reflected the RF transmission signal based on the range spectrum calculated based on the demodulated signal; a behavior detection unitconfigured to detect behavior of the object based on the range spectrum; a fixed object specifying unitconfigured to specify a fixed object from among detected objects based on the distance and behavior; and a virtual image specifying unitconfigured to, if there are two or more objects other than the fixed object among the detected objects, calculate a degree of similarity in the change over time in the behavior for each combination of the objects other than the fixed object, and specify a virtual image based on the degree of similarity.
