duct propagation मीनिंग इन हिंदी

उदाहरण वाक्य

1. It is concluded from the investigations that evaporation duct propagations and other tropospheric duct propagations become very complicate multi - discipline problems at present time including em theory , atmospheric science and applied science etc . , and one of the tough and hot issues in the field of tropospheric propagation
2. In terms of deriving the maximum trapped - wavelength and the critical emitting angle of elevation for electromagnetic wave which can forms duct propagation and introducing the four kinds necessary condition for electromagnetic wave to form duct propagation , under these conditions we now have the radio wave bent back towards the earth
3. According to state - of - the - art of evaporation duct propagation research , and to meet the demands on the prediction techniques of evaporation duct environment and the assessment of radar performance under evaporation duct environment , this dissertation gives a thorough research in depth on the subject described above . the researches include the prediction theory of evaporation duct and its applications , the theory of ray tracing based on which the prediction of radio wave rays are conducted and its application to the predicting of radar range performance under a given evaporation duct , and the characteristics of tropospheric ducts over china
4. The result can be long distance reception of radio waves that would normally have been far beyond the radio horizon . the equations for ray tracing were given , simulating and tracing electro - magnetic wave duct propagation using spherical layered atmosphere mode , this method is very useful for analysis of radar echo distribution and confirm relation of stratification of atmosphere and ray duct propagation in the process of studying radar second product , introduce a new 3 - d interpolation method . outcome of this method can suit all kinds of density product
