Assimilation of ice and water observations from SAR imagery to improve estimates of sea ice concentration [PDF]

open access: yesTellus: Series A, Dynamic Meteorology and Oceanography, 2015
In this paper, the assimilation of binary observations calculated from synthetic aperture radar (SAR) images of sea ice is investigated. Ice and water observations are obtained from a set of SAR images by thresholding ice and water probabilities ...

Interference mitigation in passive microwave radiometry [PDF]

open access: yesIEEE International Geoscience and Remote Sensing Symposium, 2003
Relentless development of the microwave spectrum for telecommunications and other active services enhances the risk of anthropogenic interference to the passive Earth Exploration Satellite Service (EESS). While spectral allocation remains the primary basis for avoiding interference between the passive and active services, it is also prudent to consider

Efficient enhancements in spectral domain method to speed up open planar circuit analysis [PDF]

open access: yes, 1998
The spectral domain method is a very fast and powerful technique to analyse planar microwave circuits. Available techniques for simulating the excitation of open planar microwave circuits are not very effective at relatively low frequencies.
