According to the spectral shift principle, distributed scatterers can be coherently observed by ERS and ENVISAT SAR systems despite of their carrier frequencies 31 MHz frequency shift. A 2km normal baseline should be set in order to compensate such a carrier frequency difference for almost horizontal terrain. This type of SAR interferometry configuration can be usefully exploited to get DEMs of rolling topographic features with very high vertical accuracy. This experiment has been carried out using an ERS-ENVISAT interferometric pair with a normal baseline of about 1.5km (the 31MHz frequency shift is partially compensated on cross-track terrain slopes ranging from 0 to 7 degrees) and a very short (30 minutes) temporal separation, thus containing the temporal decorrelation to acceptable values.
