Electromagnetic wave imaging method, apparatus, and system

An electromagnetic wave imaging apparatus, comprising:

• at least one processor;
• a transceiver, configured to:
• collect electromagnetic echo signals at a first plurality of moments, to obtain a plurality of electromagnetic echo signals, wherein each electromagnetic echo signal indicates electromagnetic wave scattering feature information of a target object, and the plurality of electromagnetic echo signals indicate a plurality of pieces of electromagnetic wave scattering feature information;
• and
• a non-transitory computer-readable storage medium storing a program to be executed by the at least one processor, the program including instructions to:
• obtain location information of reception points of the electromagnetic echo signals at a second plurality of moments, to obtain a plurality of pieces of location information, wherein each piece of location information indicates relative location information between a respective reception point and a positioning label;
• and
• perform electromagnetic wave imaging on the target object based on the plurality of pieces of electromagnetic wave scattering feature information and a correspondence between the plurality of pieces of location information and the plurality of pieces of electromagnetic wave scattering feature information;
• and
• wherein the first plurality of moments meet a first period, the second plurality of moments meet a second period, and there is a multiple relationship between the first period and the second period.

A system comprising:

• an electromagnetic echo signal collection module, configured to collect electromagnetic echo signals at a first plurality of moments to obtain a plurality of electromagnetic echo signals, and output first information to an imaging module, wherein each electromagnetic echo signal indicates electromagnetic wave scattering feature information of a target object, the plurality of electromagnetic echo signals indicate a plurality of pieces of electromagnetic wave scattering feature information, and the first information comprises the plurality of pieces of electromagnetic wave scattering feature information of the target object;
• a self-positioning module, configured to obtain location information of reception points of the electromagnetic echo signals at a second plurality of moments, to obtain a plurality of pieces of location information, and output the plurality of pieces of location information to the imaging module, wherein each piece of location information indicates relative location information between the respective reception point and a positioning label;
• and
• the imaging module, configured to perform electromagnetic wave imaging on the target object based on the plurality of pieces of electromagnetic wave scattering feature information and a correspondence between the plurality of pieces of location information and the plurality of pieces of electromagnetic wave scattering feature information;
• and
• wherein the first plurality of moments meet a first period, the second plurality of moments meet a second period, and there is a multiple relationship between the first period and the second period.
