Radiometric measurements of the microwave emissivity of foam were conducted in May 2000 at the Naval Research Laboratory's Chesapeake Bay Detachment using radiometers operating at 10. polarization measurements were obtained at 10.8 GHz. Surface foam was generated by blowing compressed air through gas permeable tubes supported by an aluminum frame and(More)
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)
[1] The relationship between microwave imaging radar measurements of fluid velocities in the surf zone and shoaling, breaking, and broken waves is studied with field observations. Normalized radar cross section (NRCS) and Doppler velocity are estimated from microwave measurements at near-grazing angles, and in situ fluid velocities are measured with(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)
