abstract = "Previous analysis of PALSAR image suggests a residual morphology
related to a possible wave-dominated delta to the north of the
Para{\'{\i}}ba River mouth. If confirmed, this feature can
contribute with studies aiming the reconstruction of relative sea
level fluctuations during the late Quaternary in northeastern
Brazil. The PALSAR sensor operates in the L band (23, 6 cm) and
has good penetrability in ground targets, being able to unraveal
morphological features not identifiable using other remote sensing
products. Given the relatively recent availability, the
application of PALSAR images aiming the recognition of deltaic
morphologies has not been tested yet. The goal of this work was to
test spatial filtering techniques based on PALSAR images in order
to analyze their potential for the recognition of deltaic
morphologies, using as an example a residual paleodelta morphology
at the Para{\'{\i}}ba River mouth. Arithmetic operations and
spatial filtering techniques (mean and directional) based on HH
and HV polarizations were applied. The results were evaluated by
descriptive statistics and target characteristics such as
brightness, texture and contrast. The remote sensing techniques
used in this work highlighted the residual deltaic morphology of
the Para{\'{\i}}ba River and helped to characterize its
sub-environments. In particular, the HH and HH+HV polarized images
processed using spatial filtering techniques were the most
efficient products to delineate the paleoshoreline of this deltaic
system, and also the sets of beach ridges that prograded during
its evolution.",
