A dual-beam along-track interferometric synthetic aperture radar which is entirely self-contained within an aircraft pod has been developed by the University of Massachusetts to study sea surface processes in coastal regions. The radar operates at 5.3 GHz with a bandwidth of up to 25 MHz. System hardware is described. Initial test flights aboard the NOAA(More)
—The dual-beam interferometer is an airborne instrument that combines two vertically polarized C-band along-track interferometric synthetic aperture radars (AT-InSARs) observing the surface below at different squints. The system was designed by the University of Massachusetts and saw several deployments in the early 2000s. An imagery of a small vessel with(More)
—This paper summarizes an analysis of gradient-induced distortions in the surface current estimates generated by along-track interferometric SAR (ATI-SAR) systems. In the presence of spatial current gradients, an effect akin to velocity bunching can cause distortion in the measured current profiles. This distortion is caused by variation in the azimuthal(More)
