1. An electromagnetic wave imaging method, comprising:
collecting, by an electromagnetic wave imaging apparatus, 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;
obtaining 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 the respective reception point and a positioning label; and
performing 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.
