Rain fade slope predicted from rain rate data

Radio Science, 2007

A key parameter of the statistics of the rate of change of rain attenuation (“fade slope”) on satellite links is the variance of relative fade slope. This paper shows how this parameter can be derived from rain rate measurements without the use of satellite beacon measurements. Relating rain rate directly to attenuation would give unrealistic results. A theoretical model to ...

  • Rain fade slope predicted from rain rate data

    A key parameter of the statistics of the rate of change of rain attenuation (“fade slope”) on satellite links is the variance of relative fade slope. This paper shows how this parameter can be derived from rain rate measurements without the use of satellite beacon measurements. Relating rain rate directly to attenuation would give unrealistic results. A theoretical model to estimate the variance of relative fade slope is derived, using the integrating effect of rain rate variations along the propagation path and using as inputs several meteorological parameters only. The theoretical values are compared to measured results from a link in the United Kingdom at 50 GHz. The agreement is good on average and also in their correlation with the type of rain and with the rain height. With the wind speed, the theoretical values increase more strongly than the measured results, which may be due to the limited spatial resolution of the meteorological data.

  • Liquid water content estimates using simultaneous S and K<inf>a</inf>band radar measurements

    A technique for the estimation of total liquid water content (LWC; the sum of cloud water and rainwater contents) using simultaneous S and Kaband scanning radar observations is proposed and tested using the National Center for Atmospheric Research simultaneous S band and Kaband dual-polarimetric (S-PolKa) radar system. The sources of error for this wavelength pair are evaluated, and the methods to mitigate them are discussed. The results are LWC estimates at each radar volume that are equivalent to specifying a reflectivity (Z) – LWC relation constrained by the measured attenuation over 2 km radar ray segments. Because the radars are scanning, the LWC can be mapped out over the spatial volume and temporal evolution of the clouds. The method produces reasonable results that qualitatively compare well to in situ aircraft observations.

The proposed model allows generating rainy and not rainy conditions for multiple stations in a large geographical area, reproducing the actual spatial and temporal variability of the rain process, with limited computational effort. Single site and joint statistics of rain attenuation obtained by the time series of measurements are discussed. The model is used to show the effectiveness, in terms of link margin, of gateway networks in smart diversity arrangement, for different separation distances among sites.

  • Disturbance attenuation and rejection for systems with missing measurements via DOBC approach

    For a class of nonlinear systems with missing measurements and multiple disturbances, Disturbance attenuation and rejection problems are investigated in this paper. The state observer and disturbance observer are constructed based on measurement output error and/or control input. The measurement output may occur to loss in the real systems, which are characterized by stochastic binary sequence. Two types of disturbances are also considered, one is emerged from H2form, which are attenuated by H∞control. The other is rejected by disturbance-observer-control. The pth(1, 2) moment exponential stability are analyzed in terms of linear matrix inequalities (LMIs) for the systems with known nonlinear dynamics. Simulation examples are provided to demonstrate the effectiveness of the results.

  • Attenuation computer tomography by phase insensitive detection

    A large, one dimensional receiving array has been developed in the attenuation projection measurement and the phase insensitive (PIS) data processing method has been used in the evaluation. Our aim of this study is to suppress the corresponding artifacts in the attenuation projection. Four different cylindrical, biomaterial objects are tested in the measurement. The results are compared with phase sensitive (PS) results. The conclusion is given in the last part.

  • Increasing TWTs' electronic efficiency

    A possibility of a significant increase in the electronic efficiency of TWTs is considered in this paper. The output power and the power at the attenuator of a two-section TWT are measured, simulated, and calculated analytically at a fixed frequency for different distances between the attenuator and the output terminal. The significant difference between the output power and power at the attenuator's input is explained by the e-beam intensive interaction with the wave in the absorbing section. Attenuators with decreased interaction impedance are offered to increase the TWT's electronic efficiency.

  • Ground Loops During Site Validation of Anechoic Rooms Below 30 MHz

    Building up a ground loop is a very common mistake when validating anechoic rooms below 30 MHz, because this is not an issue in the frequency ranges above. It is required to measure a Site Attenuation of nearly 120 dB, but a ground loop can limit this to 63.1 dB. So a large systematic error will occur. There are several possibilities to avoid a ground loop by using battery powered devices, an isolation transformer or an RF transformer. Special care has to be taken to recognize all ground loops which can be formed by communication cables and reference frequency links. Also, a ground loop can be formed by the installed cables which are routed below the ground plane.

  • Calculations of wave propagation on a helix in the attenuation region

    It is a well-known fact that the attenuation region of the traveling-wave tube is very important to the performance of the tube, particularly with respect to gain and efficiency of the tube which is relatively short in terms of wavelengths. Characteristics of the attenuator in the passive tube have been measured frequently and variations of attenuation and wave velocity with respect to frequency and thickness of coating are known. In the interests of trying to understand the effect of the attenuator on efficiency, we have attempted to make certain calculations of performance of a theoretical attenuator such as is frequently used on certain spirals and the results of such calculations are presented here.
