The acquisition unit (210) acquires an IF signal from an irradiation apparatus (10) at a plurality of timings. The likelihood information generation unit (220) executes, by processing the IF signal, processing of generating, with respect to each of a plurality of IF signals, likelihood information for a region (hereinafter, referred to as a target object region) having a possibility in that an accompaniment, i.e., a target object is present. The likelihood information indicates a distribution of presence probabilities of a target object in at least a height direction in a target object region. Then, the determination unit (230) determines a presence or absence of a target object, by using likelihood information generated for each of a plurality of target object regions.

Abstract: A radar signal transmission/reception unit (103) acquires a radar signal generated by using a plurality of transmission antennas Tx and a plurality of reception antennas Rx. A projection direction/imaging policy control unit (107) holds an imaging policy. The imaging policy includes a projection direction representing a direction in which an inspection target is viewed, an imaging area indicating an area of which a three-dimensional radar image is to be generated, and set information being information on a set of pairs of a transmission antenna Tx and a reception antenna Rx for use in generation of the three-dimensional radar image. An imaging unit (104) generates the three-dimensional radar image from the radar signal in accordance with the imaging policy. A projection processing unit (106) forms the three-dimensional radar image into a two-dimensional image by projecting the three-dimensional radar image in the projection direction indicated by the imaging policy.
