Modeling and Simulation RF Systems Training covers principles behind RF System modeling and simulation plus modeling and simulation of Radar, Microwave and Electronic Warfare systems.

Learn how to use modeling and simulation to solve complexity in Defense, Aerospace and Commercial Industries. There are numerous design challenges faced by RF system engineer while working on analysis and design.

Programs are prone to errors during Requirements and Design Definition phases. Also as designs grow and change, maintaining requirements becomes an uphill task. Model based approach in RF and Radar Engineering has ability to detect defect at much more early stage than conventional methods.

Model Based RF and Radar Engineering, using simulation and modeling techniques, includes various logical and physical tools, block diagrams, state machines, mathematical equations, functional flow diagrams, object-oriented models to help to understand various RF and radar subsystems.
