Radargrammetric 3-D Reconstruction of Multiple Moving Ship Targets via Multiangle Spaceborne SAR Imagery

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The increasing complexity of the marine environments imposes higher demands on the surveillance of maritime ships. Radargrammetry can extract the height information of targets from the amplitude of multiangle synthetic aperture radar (SAR) imagery, which

Imaging of targets beneath foliage with SAR tomography [PDF]

open access: yes, 2008
SAR tomography (SARTom) is an imaging technique that allows multiple phase centre separation in the vertical (height) direction, leading to a 3-dimensional (3D) reconstruction of the imaged scene. It is usually performed after standard 2D SAR repeat-pass

An Improved Ultrahigh-Resolution Stepped-Frequency Spaceborne SAR Imaging Algorithm

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Frequency stepping is a widely used technique for ultrahigh-resolution synthetic aperture radar (SAR). Although reducing the burden of hardware, this technique increases the complexity of imaging algorithms due to the intersubband time offsets and ...
