InSAR time series analysis of deformation fields almost always starts with processed range-Doppler single look complex (SLC) radar images. These images are then co-registered and pairwise phase differences form the interferograms. Computing coregistered SLCs directly in a desired geometry saves significant data storage and readily produces data products that are easy to analyze in coordinate systems that are well matched to a desired application. Here we demonstrate InSAR data products created using a backprojection algorithm that skips the range-Doppler, coregistration, and elevation compensation steps, greatly simplifying analysis by the end user and opening up InSAR techniques to a wider group of applications.
