Rf ortam simülatörü

Evolution of modern communications and radar systems have increased the demand on modelling the propagation effects with real world scenarios for various signal types. The main purpose of this study is to create a flexible, generic and realistic Radio Frequency (RF) environment simulator mainly for radar and communication signals. Software defined radio (SDR) platform has been preferred for generating the simulated signals at radio frequencies. Multipath fading, interference and noise have been calculated for multiple signals simultaneously and generated via RF outputs of the SDR. RF outputs of the proposed configuration are suitable for use in the tests of receivers such as direction finding systems, electronic intelligence, and Long-Term Evolution (LTE) Multiple Inputs Multiple Outputs (MIMO) systems. Communication quality for several signal types has been experimentally investigated with various terrain profiles and fading scenarios using existing vector signal generators, vector signal analyzers, demodulation and communication analysis tools. This simulation platform can be used in Electromagnetic Compatibility tests of such systems as well.
