Radar atmosphere sounding, digital processing of radar signals, models of scattered signalsAbstract
The article describes the models of signals scattered by atmospheric inhomogeneities. These models are used in simulation modeling to test the methods of signal processing in radar systems of atmosphere vertical sounding, as well as during the development of assessment methods of the scattered signals parameters and methods of inhibition of active and passive noises. The application of a more complex model, which describes the properties of the scattered signals, allows reducing the errors of assessment of meteoparameters by radar systems of atmosphere vertical sounding. The complication of models and methods of processing put the problems of optimization of computational procedures of signal processing. One of the approaches that achieve the required performance under these conditions is the use of parallel computing systems - universal and graphics processor, and clusters. This approach is discussed in this article. The main purpose is to study the possibility of effective implementation of procedures for processing of radar signals based on parallel computation systems. In the study we used the method of simulation modeling and statistical processing of the results. The signals processing methods, which used during their development a physical model of scattering, provide lesser value of the error of assessment of the parameters of atmosphere. The research results can be used in development and modernization of processing systems of radar signal of atmosphere vertical sounding. The application of graphic processors for signal processing allows obtaining the results in real time using a physical model of scattering - the most detailed model of the formation of signals in radar systems of vertical soundingReferences
