Radar apparatus, imaging method, and non-transitory computer-readable medium

An imaging method comprising,

• by a computer:
• radar signal transmission/reception processing of acquiring a radar signal generated by using a plurality of transmission antennas and a plurality of reception antennas;
• projection direction/imaging policy control processing of holding an imaging policy including 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 and a reception antenna for use in generation of the three-dimensional radar image;
• imaging processing of generating the three-dimensional radar image from the radar signal in accordance with the imaging policy;
• and
• projection processing of forming the generated three-dimensional radar image into a two-dimensional image by projecting the generated three-dimensional radar image in the projection direction indicated by the imaging policy.

A non-transitory computer-readable medium storing a program for causing a computer to perform operations, the operations comprising:

• acquiring a radar signal generated by using a plurality of transmission antennas and a plurality of reception antennas;
• holding an imaging policy including 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 and a reception antenna for use in generation of the three-dimensional radar image;
• generating the three-dimensional radar image from the radar signal in accordance with the imaging policy;
• and
• forming the generated three-dimensional radar image into a two-dimensional image by projecting the generated three-dimensional radar image in the projection direction indicated by the imaging policy.
