T1 MILLIMETER AND TERAHERTZ WAVE SCATTERING DIAGRAMS IN RAINS JF Telecommunications and Radio Engineering JO TRE YR 2015 FD 2015-12-11 VO 74 IS 13 SP 1157 OP 1166 K1 scattering diagram K1 remote sensing K1 rain drop size distribution function K1 terahertz frequency range AB Detailed information about millimeter and terahertz wave scattering diagrams in rains is needed to develop millimeter and terahertz range radio engineering systems. It is rather difficult to measure scattering diagrams, the easier way is to calculate them. The prepared tables of scattering diagrams can be used for microwave range, but there are no such data for the terahertz one. This paper presents the results of scattering diagram calculation of millimeter and terahertz waves by raindrops. The calculations were using the exact formulas for the entire range of raindrop sizes appeared in precipitation. Database of scattering diagrams was developed on the basis of obtained results. It gives a wide opportunity for calculation of scattering diagrams at various combination of initial data, i.e., wave length, raindrop size distribution and rain intensity. The obtained results may be used for estimation of radiation power spatial distribution in millimeter and terahertz ranges.
