Radio frequency imaging apparatus and method

A radio frequency imaging apparatus, wherein the radio frequency imaging apparatus comprises:

• a radio frequency receiver means, which is configured receive radio frequency electromagnetic radiation interacted with a non-stationary object and form, as a function of time based on tomography, at least one property of the radio frequency radiation interacted with and passed through the object that blocks partly the propagation of the radio frequency radiation through the object, the non-stationarity of the object relating to at least one of the following:
• a direction of the radio frequency radiation with respect to the object, a position of the receiver means;
• data gathering means, which is configured to gather information on position and/or orientation of the object as a function of time, and form as a function of time, information on position and/or orientation of the object within the radio frequency radiation from the gathered data;
• and
• a data processing means, which is configured to form at least one radio frequency image of the object from both of said information on position and/or orientation of the object and the at least one property of the object based on the radio frequency radiation interacted with the object and inside of the object, the data processing means being configured to utilize temporal relation between the at least one radio frequency property and information on the position and/or orientation of the object in formation of the radio frequency image.
