Abstract :	[en] As an extension of Synthetic Aperture Radar Interferom- etry, Multiple Aperture Interferometry (MAI) is a spectral diversity technique that allows the determination of azimuth displace- ments from phase shift measurements. This is made possi- ble through the creation of backward- and forward-looking Single-Look-Complex (SLC) data. Then, the phase differ- ence between the backward and forward-looking interfero- gram is translated into a displacement. Using SLC data, MAI requires a proper azimuth splitband operator. Different tech- niques exist to split the azimuth band, but they are often too briefly described in the MAI literature. In this conference pa- per, we analyze the signal properties of the Sentinel-1 TOPS acquisition mode and define an azimuth subbanding proto- col. In particular, we look at the role of de-apodization and apodization in the band filtering operation. We focus our anal- ysis on Sentinel-1 data in Interferometric Wideswath mode over the Roi Baudouin Ice Shelf, East Antarctica.
