Empirical models of the normalized radar cross section of monostatic freshwater clutter
2015 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting, 2015Empirical models of the normalized radar cross section (NRCS) of linear co-polar monostatic freshwater clutter returns are presented. The models presented are similar to empirical models developed for sea clutter and relate the estimated NRCS to environmental conditions and scenario geometry. Model parameters are found through a least-squares fit.

Ultrawideband normalized radar cross sections of distributed clutter
2012 IEEE Radar Conference, 2012Theoretical and empirical formulas have been derived to compute the normalized radar cross section (NRCS) of distributed clutter targets for remote sensing applications. These formulas are usually parameterized in terms of the center frequency, and are therefore frequency-dependent.

Normalized radar cross section measurement for space objects
2016 IEEE 11th Conference on Industrial Electronics and Applications (ICIEA), 2016Joint observation with multiple radars operating on different frequencies is beneficial to classification, identification and catalogue for space objects with multiple radars. Since RCS is sensitive to frequencies, RCS would be considerably different for the same space object measured by radars operating on different frequencies; this effect is not ...

A user-friendly computer program has been developed that is useful in archiving and graphically plotting normalized radar cross sections (NRCS) of geophysical surfaces. The program, called FINRACS, utilizes a data base, which includes data obtained by the radar community during the past 30 years. Users can store and retrieve data according to frequency

From the first-order small slope approximation, thispaper presents a closed-form expression of the sea backscatteringNRCS (normalized radar cross section) versus the skewnessfunction to predict the upwind-downwind asymmetry. This effectis produced by the fact that the surface height distributionslightly deviates from a Gaussian one.

C band microwave radars have been widely used in ocean observations, e.g. oil spill monitoring, ship detection, wind speed retrieval, etc. All these applications rely on the measured normalized radar cross section (NRCS) of sea surface. Therefore, it is necessary to develop accurate models to predict the radar cross sections of sea surface.

Correction of SeaWinds Normalized Radar Cross Sections for improved coastal winds
2022 IEEE International Workshop on Metrology for the Sea; Learning to Measure Sea Health Parameters (MetroSea), 2022This paper presents a new methodology to correct the land-contaminated normalized radar cross-section (\sigma_{0}) measurements acquired by the SeaWinds scatterometer, which flew onboard the QuikSCAT satellite platform from 1999 to 2009, operated by the National Aeronautics and Space Administration (NASA).
