Opt. Lett.Volume:v 5Issue:n 4Issue date:April 2007Publication year:2007Pages:p 245-248Language:EnglishISSN:1671-7694Document type:Journal article (JA)Publisher:Science Press, Beijing, 100085, ChinaAbstract:The scattered field and differential scattered section (DSS) of a moving spherical particle with a high speed are investigated numerically. The coordinate and vector transformations are used to establish a theoretical basis for studying the laser scattering of a moving particle. The DSS of a moving spherical particle is explained by the electric and magnetic field from Mie scattering theory. Assuming the laser wavelength of 1.06μm, we compute the ratio of the laser DSS of the moving dielectric spherical particle to that of the static dielectric spherical particle, which changes with radii, speeds and scattering angles of the particle. The numerical results show that the laser DSS of the moving spherical particle is tightly connected with its speed and scattering zenith angle. If a spherical particle moves with high speed, the laser DSS due to movement of the particle could not be neglected. If the speed of the dielectric spherical particle is fluctuating, the Doppler effect and the frequency spectrum expansion play important roles.Number of references:13Ei main heading:Light scatteringEi controlled terms:Dielectric materials - Doppler effect - Magnetic fields - WavelengthUncontrolled terms:Differential scattered section (DSS) - Laser scatteringEi classification codes:701.2 Magnetism: Basic Concepts and Phenomena - 708.1 Dielectric Materials - 741.1 Light/OpticsTreatment:Theoretical (THR)Database:CompendexCompilation and indexing terms, Copyright 2007 Elsevier Inc.

The pulse fluctuation characteristic and the pulse broadening effect are investigated. The function relation of pulse group velocity with frequency and rain rate is obtained. The effects induced by the EM wave frequency and bandwidth on the pulse broadening velocity is studied and the simulated results are given in the mm band. The results show, based on the calculation in this paper, that the pulse broadening velocity of horizontal polarization wave is greater than that of the vertical polarization wave and that the pulse broadening velocity increases with an increase in bandwidth and rain rate.Number of references:7Ei main heading:Electromagnetic wave transmissionEi controlled terms:Polarization - RainUncontrolled terms:Rain medium - Pulse wave - Double frequency correlation function - Broadening - Transmission function - Pulse fluctuation - Pulse group velocity - Rain rate - Pulse broadening velocity - Polarization waveEi classification codes:711.1 Electromagnetic Waves in Different MediaTreatment:Theoretical (THR)Database:CompendexCompilation and indexing terms, Copyright 2007 Elsevier Inc.

Author affiliation:Box 273, School of Science, Xidian University, Xian 710071, China Serial title:Journal of Electromagnetic Waves and ApplicationsAbbreviated serial title:J Electromagn Waves ApplVolume:v 18Issue:n 5Publication year:2004Pages:p 627-635Language:EnglishISSN:0920-5071CODEN:JEWAE5Document type:Journal article (JA)Publisher:VSP BVAbstract:As a target is immersed in the rain medium, its detection and identification become difficult due to that scattering wave from the target is mixed with echoes from raindrops. These clutters induce a strong effect in millimeter wave band and the signal-versus-clutter ratio (SCR) is therefore deteriorated at the receiving terminal. In this paper, Lagrange multiplier method combined with iteration method is proposed to calculate the optimal polarization characteristics both for the transmitting and receiving antennas of radar to improve SCR for the coated target in rain medium. As an application for the method, polarization status of antennas with best SCR both for co-polarization channel and cross-polarization channel are obtained utilizing the rain statistic data of Xian, China. This hybrid method for calculating polarization parameters has applications in self-adaptive polarization matching of antenna in the electrical system.Number of references:4Ei main heading:Millimeter wavesEi controlled terms:Light polarization - Electromagnetic wave scattering - Radar antennas - Iterative methods - Lagrange multipliers - Frequency domain analysis - Matrix algebra - Computer simulationUncontrolled terms:
