Estimation of the Surface Velocity Field of Temperate Glaciers Using Airborne SAR Interferometry [PDF]
, 2008 This paper presents a methodology to process airborne interferometric SAR data to measure surface velocity fields of temperate glaciers. First, a solution based on multi-squint is proposed to estimate residual motion errors (inaccuracies of the ...

Digital Beamforming and Non-Uniform Displaced Phase Centre Sampling in Bi- and Multistatic SAR [PDF]
, 2004 The displaced phase centre (DPC) technique will enable a wide swath SAR with high azimuth resolution. In a classic DPC system, the PRF has to be chosen such that the SAR carrier moves just one half of its antenna length between subsequent radar pulses ...

An Improved Ultrahigh-Resolution Stepped-Frequency Spaceborne SAR Imaging Algorithm
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingFrequency 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 ...
