[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.
