OBJECT RADIOGRAPHY DEVICE, CONTROL CIRCUIT, STORAGE MEDIUM, AND OBJECT RADIOGRAPHY METHOD

WIPO Patent Application WO/2022/162868

A1

This object radiography device (10) comprises a transmitter (1) for outputting a transmission signal corresponding to a radio wave to be transmitted to an object (T), a receiver (4) for converting a radio wave that has been reflected by the object (T) and received into a reception signal represented using complex numbers, a signal separation unit (5) for separating the reception signal into a plurality of reception signals, a complex image generation unit (6) for generating complex images represented using complex numbers from each of the separated reception signals, and a complex image combination unit (7) for generating a radiographic image of the object by combining the complex images.
