Method and apparatus for compensating for a parameter change in a synthetic aperture imaging system

摘要

There is described a method for processing data generated by a synthetic aperture imaging system, comprising: receiving raw data representative of electromagnetic signals reflected by a target area to be imaged; receiving a parameter change for the synthetic aperture imaging system; digitally correcting the raw data in accordance with the parameter change, thereby compensating for the parameter change in order to obtain corrected data; and generating an image of the target area using the corrected data.

1. A method for processing data generated by a synthetic aperture imaging system, comprising:
receiving raw data representative of electromagnetic signals reflected by a target area to be imaged; receiving a parameter change causing a variation of an interference pattern parameter for said synthetic aperture imaging system, said interference pattern parameter being one of a Fresnel zone plate focal length and a Fourier slice scaling parameter; using a processing unit, digitally correcting said raw data in accordance with said parameter change, said correcting comprising determining a scaling factor using said parameter change and scaling said raw data in accordance with said scaling factor, thereby compensating for said parameter change in order to obtain corrected data; and generating an image of said target area using said corrected data, said generating comprising:
generating an incident light;modulating said incident light in accordance with said corrected data, thereby obtaining a modulated light; andoptically processing said modulated light, thereby obtaining an optical image of said target area.
