RADCOM
|
Radar and Communications Electromagnetic Compatibility Analysis Program
|
Intersite |
Designed for performing electromagnetic compatibility (EMC) analyses on radar and communication systems. RADCOM has five analysis modules: two system analysis modules, the Radar Analysis Capability (RAC) and the Communications Analysis Capability (CAC), and three ancillary modules, the Frequency-Dependent Rejection Calculation (FDRCAL), Receiver Performance Prediction (REPP), and Propagation Prediction (PROP) modules. The RAC and CAC provide for system-level assessment of potential for electromagnetic interference (EMI), whereas the ancillary modules provide for analysis on limited aspects of the overall electromagnetic compatibility (EMC) assessment. RADCOM also has the capability to interface with Microsoft Excel worksheets so that its features can be used as a tool to aid in frequency-environment analyses. RADCOM is a one-on-one analysis tool - it assesses the effects from a single radar or communications interferer on the system being analyzed. Inherent in RADCOM is the capability to account for frequency agility and antenna motion (scanning) of either interferer or receiver system. RADCOM also has the capability to account for interference losses resulting from filtering and/or processing in the receiving system. Predictions of propagation path loss are made primarily using the free-space equation, a smooth-earth model, or a rough-earth model, although provisions are also made for using the path loss that may be provided by outside sources. The smooth-earth model used by RADCOM is the Spherical Earth Model (SEM). The rough-earth model is the Terrain-Integrated Rough-Earth Model (TIREM).
