  1. Thanks for help. I'll try to get the best parts from my variant and from post #19 and soon show the last version.
  2. But I cant simply change of to and because the enumerated characteristics are charecteristics OF ionospheric channel. Great thanks for everybody for quick help!!!
  3. also i'm in doubt about these terms: gain–frequency characteristics distance-frequency characteristics angular–frequency characteristics
  4. Beta version of these translation. What do u think of it: Investigation of gain, distance, angular–frequency characteristics(responses) of midlatitude ionospheric paths has been carried out. This work contains experimentally obtained characteristics and ones from simulation modeling of propagation processes on radio paths used in experiments. Comparative analysis of real and model characteristic has been done. In this work a new technique for calculating angular-frequency characteristic from distance-frequency characteristic is developed and implemented. The developed method has been tested using direct measurements of angle-of-arrival.
  5. Does anybody understand my last post? Are there any russians here?
  6. Проведено исследование дистанционных, амплитудных, угловых характеристик ионосферного радиоканала на среднеширотных трассах различной протяженности и ориентации. Работа содержит результаты экспериментальных исследований указанных частотных характеристик ионосферного радиоканала и результаты имитационного моделирования процессов распространения на трассах, участвующих в экспериментах. Разработана методика пересчета дистанционно-частотных в угловые-частотные характеристики. Осуществлено тестирование методики прямым измерением углов прихода.
  7. Ok I try to correct this and post new version again in 15 minutes. Thank a lot.
  8. Maybe there are another terms for gain-frequency characteristic, angle-frequency characteristic, distance-frequency characteristic
  9. The purpose of the work was investigation of different characteristics(gain-frequency characteristic, angle-frequency characteristic, distance-frequency characteristic) of ionospheric radiochannel. Experiments had been carried out on different paths of propagation, on different routes of propagation I don’t know what is the proper name for it. Paper contains results of these experiments and results of simulation modeling of these experiments with use of our model based on IRI-2001(international reference ionosphere). So the purpose of modeling was to compute all these characteristics and then compare with experimental results. Then we can conclude that our model works fine . And at last we develop new technique of calculation angular-frequency characteristic from distance-frequency characteristic and test this technique for correctness.
  10. Ok maybe I try to formulate the meaning of it in my words and then you'll help me to rephrase it. Ok?
  11. It's not a google translation but another program
  12. I know that it's horrible thats why I'm calling for help.
  13. I have an abstract in Russian and I must translate it in English. There is very BAD translation and I try to correct it. Can you help me. Research of distance, gain, angular characteristics of ionospheric radio channel on middle-latitude routes of various extent and orientation has bee done. Paper contains results of experimental researches of the specified frequency characteristics of ionospheric radio channel and results of simulation modeling of processes of distribution on the routes participating in experiments. The technique of recalculation distance-frequency characteristic in angular-frequency characteristic is developed. Testing of this technique has been done.
  14. Native speakers, please, check the following abstract of the article. Are there any mistakes? Research of distance, gain, angular characteristics of ionospheric radio channel on middle-latitude routes of various extent and orientation is lead. Work contains results of experimental researches of the specified frequency characteristics of ionospheric radio channel and results of simulation modeling of processes of distribution on the routes participating in experiments. The technique of recalculation distance-frequency characteristic in angular-frequency characteristic is developed. Testing of this technique has been done.
