We recently received a request for burst InSAR products to include an amplitude image like we provide in our GAMMA-based InSAR products with this justification:

In the context of time series InSAR processing, the inclusion of amplitude information holds paramount importance. It serves as a fundamental resource for various critical tasks, including the identification of stable targets and the validation of statistically homogeneous families, thereby contributing substantially to the overall efficacy and accuracy of the analysis.
