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
Experimental detection of an ELF radio pulse associated with the gamma-ray burst of December 27, 2004Radiophysics and Quantum Electronics - Tập 54 - Trang 15-23 - 2011

We compare the experimentally observed and model waveforms of the electromagnetic pulse associated with an abrupt change in the height of the Earth–ionosphere cavity, which was caused by an intense gamma-ray burst that arrived from the cosmic source in December 27, 2004. Polarization and spectral properties of the burst are examined. It is shown that the experimentally observed extremely low frequ...... hiện toàn bộ
