Abstract
A process for generating synthetic aperture radar interferograms comprises the following steps. First and a second radar images of a scene from a first and a second position spaced apart by a given baseline are generated. A first signal of said first image within a first radio frequency band of the spectrum is recorded. A second signal of said second image within a second radio frequency band of the spectrum having a frequency shift relatively to the first detecting band is recorded. The frequency shift being such that it ensures or maximizes correlation between the first and the second images. The first and second signals are combined for generating an interferogram of said scene.

A process for generating synthetic aperture radar interferograms comprising the steps of:
- generating a first and a second radar image of a scene from a first and a second position spaced apart by a given baseline,
- recording a first signal of said first image within a first radio frequency band of the spectrum,
- recording a second signal of said second image within a second radio frequency band of the spectrum having a frequency shift relatively to said first detecting band, said frequency shift being such that it ensures or maximizes correlation between the first and the second images,
- combining said first and second signals for generating an interferogram of said scene.
