Abstract: Disclosed is an image data generating method. Operations of emitting electromagnetic waves to an object and receiving scan signals scanning the object are performed by using a multi-static transceiver. First image data of a low resolution are generated based on the scan signals. when a first condition associated with the first image data is satisfied, second image data of a high resolution associated with a sub-region of the first image data are generated. When a second condition associated with the second image is satisfied, third image data based on the first image data and the second image data are generated.

Abstract: Disclosed is an image generating device, which includes a measurement device including a plurality of transmitters and a plurality of receivers for a multistatic measurement of an object, an image preprocessing device that receives a raw image signal corresponding to the multistatic measurement from the measurement device and generates a preprocessed image signal based on the raw image signal, an image amplifier that generates an amplified image signal based on the preprocessed image signal, and an image restorer that generates a restored image signal corresponding to the object based on the amplified image signal, and the image amplifier is further configured to set up a first virtual transmitter and a first virtual receiver, to obtain first measurement data of a first target transmitter closest to the first virtual transmitter among the plurality of transmitters and a first target receiver closest to the first virtual receiver among the plurality of receivers.
