Abstract: | Conclusion We have presented a convenient method of measurements in adjusting the parameters for distributions of raindrop sizes and obtaining canting angles to accommodate to the local geographic and meteorologic conditions to get the required data for calculation of AR and XPD in the system planning of a short ground link using millimeter wave band. The measured results had been used in a theoretical formula to compute the XPD induced by rain in ground radio link of path length 2.2km and 35.3GHz with linear polarization, and discovered that the computed XPD agreed well with the measured XPD/6/. The agreement confirms that our methods of measurements are reliable and the measurements described above at one spot in the radio path are feasible in prediction of the AR and XPD for a short ground radio link.Of course, if the accuracy of the discriminating device were improved, it would have smaller errors in discrimination, and the results obtained would be more presise.The assistance of Y.Yan, T.S. Zhang and Y. Huang in making the measurements and calculations is gratefully acknowledged. |
