Interferometric synthetic aperture radar (InSAR) ability to determine pixel elevation with a resolution derived from the interferometer phase resolution, is maintained as long as the interferometer phase change over the pixel does not exceed the phase resolution. This work investigates the surface coverage where this condition is met, determines the elevation resolution,: and derives the ratio between elevation resolution and across-track resolution.
