semiell1piricalll1odel of the norll1alized radar cross-section of the sea
Multiscale composite models based on the Bragg theOly are widely used to study the U1LlI<,,'l~"~' radar cross-section (NRCS) over the sea sllrface. However, these models are able to correctly reproduce the NRCS in ail configurations and wind wave conditions. have developed a physical model that takes into account, not only the Bragg nisl11, but also the non-Bragg scattering l11echanisl11 associ...
متن کاملSpherical Wave Near-Field Imaging and Radar Cross-Section Measurement - Antennas and Propagation, IEEE Transactions on
The paper presents a new inverse synthetic aperture radar (ISAR) algorithm intended for radar cross-section (RCS) imaging and measurement from scattered fields. The method, based on a spherical-wave near-field illumination of the target, overcomes the requirement for an expensive compact range facility to produce a plane wave illumination. The formulation and the implementation of the algorithm...
متن کاملEstimation of Radar Cross Section of a Target under Track
In allocating radar beam for tracking a target, it is attempted to maintain the signal-to-noise ratio (SNR) of signal returning from the illuminated target close to an optimum value for efficient track updates. An estimate of the average radar cross section (RCS) of the target is required in order to adjust transmitted power based on the estimate such that a desired SNR can be realized. In this...
متن کاملActive Calibration Target for Bistatic Radar Cross-Section Measurements
Either passive calibration targets are expensive and complex to manufacture or their bistatic RCS levels are significantly lower than the monostatic RCS levels of targets such as spheres, dihedraland trihedral corner reflectors. In this paper the performance of an active calibration target with relative high bistatic RCS values is illustrated as a reference target for bistatic RCS measurements....
