Spectral characteristics of a microwave radar signal backscattered by the sea surface at small incidence anglesRadiophysics and Quantum Electronics - Tập 39 - Trang 347-352 - 1996
M. B. Kanevskii, V. Yu. Karaev
We present a theoretical analysis of the Doppler-spectrum properties of a microwave radar signal scattered by the sea surface at small incidence angles. The dependences of Doppler-spectrum width and shift on the wind velocity and wave development stage and their azimuthal dependence are analyzed. The case of mixed sea (wind wave plus swell) is also considered. The JONSWAP spectrum model is used t...... hiện toàn bộ
Suppression of image artifacts in the spectral-domain optical coherence tomographyRadiophysics and Quantum Electronics - Tập 52 - Trang 810-821 - 2010
V. M. Gelikonov, I. V. Kasatkina, P. A. Shilyagin
In this paper, we review methods for obtaining in vivo optical images of bio-objects with the resolution ranged from several units to tens of micrometers, namely, the methods of spectral-domain optical coherence tomography. We focus on problems that are specific of the spectral-domain optical coherence tomography, namely, the presence of coherent noise and mirror-symmetric phantoms in the image. O...... hiện toàn bộ
