Mangrove vegetation structure in Southeast Brazil from phased array L-band synthetic aperture radar data
(Spie-soc Photo-optical Instrumentation Engineers, 2016-09-06)
The potential use of phased array type L-band synthetic aperture radar (PALSAR) data for discriminating distinct physiographic mangrove types with different forest structure developments in a subtropical mangrove forest ...
Improving synthetic aperture image by image compounding in beamforming process
In this work, signal processing techniques are used to improve the quality of image based on multi-element synthetic aperture techniques. Using several apodization functions to obtain different side lobes distribution, a ...

Sparse arrays and image compounding techniques for non-destructive testing using guided acoustic waves
Piezoelectric array transducers applications are becoming usual in the ultrasonic non-destructive testing area. However, the number of elements can increase the system complexity, due to the necessity of multichannel ...
Exploring the Capability of ALOS PALSAR L-Band Fully Polarimetric Data for Land Cover Classification in Tropical Environments
(Ieee-inst Electrical Electronics Engineers Inc, 2016-12-01)
Among different applications using synthetic aperture radar (SAR) data, land cover classification of rain forest areas has been investigated. Previous results showed that L-band is more appropriate for such applications. ...
Synthetic aperture sonar images segmentation using dynamical modeling analysis
(Sociedade Brasileira de GeofísicaRio de Janeiro, 2013)
Symbolic Models applied to Synthetic Aperture Sonar images are proposed in order to assess the validity and reliability of use of such models and evaluate how effective they can be in terms of image classiﬁcation and ...
