| This paper describes how the BAE Systems Integrated RF Development Environment RF Development Environment">(IRFDE) is used in complex RF communications and network modeling scenarios. The IFRDE is an all-encompassing software integration environment used to analyze communication system and elements, from individual radio communications, to platform systems, to complex systems comprised of a variety of radios across a wide area. RF Development Environment"> IRFDE-enabled end-to-end communication system analysis and simulation includes static or mobile scenario creation and communication link analysis at any location in the world, considering terrain and clutter effects, rain and atmospheric losses (including HF), multipath fading, Doppler shift, and shadowing. A library of pre-existing waveforms give the user the ability to model new waveforms and integrate them into a scenario. Interference and detection analysis is possible, including co-site analysis for platforms. All link types can be simulated, including point-to-point, point-to-multipoint (and vice-versa), relaying, and BLOS.
Payloads are modeled for the vehicles in a scenario, and a library of vehicles is available. The user can define a customized vehicle and payload. Radios, antennas, filters, duplexers, diplexers, amplifiers, and mixers are available. Electromagnetic analysis can be done for antenna structures, or antenna patterns can be entered manually.
Spectrum and frequency management is a feature of RF Development Environment"> IRFDE. For any scenario, RF Development Environment"> IRFDE can define and optimize frequency assignments using a variety of algorithms, taking into consideration restricted frequencies, available frequency blocks, occupied bandwidth, channelization, propagation, and interference. OPNET is integrated within RF Development Environment"> IRFDE to provide network analysis. The RF analysis is done for every discrete step within OPNET, providing an accurate model for OPNET of the channel and the waveform under the stated conditions.
There is no software tool on the market for complete end-to-end military and commercial RF communications system analysis and simulation. A myriad of tools exist to provide specific functional analysis within this scope, but only the BAE Systems RF Development Environment"> IRFDE tool integrates these functions together and provides additional desirable functions and algorithmic control. |
