Advanced RCS Analysis of Airborne Vehicles

Analysis by electromagnetic simulation allows the designer to characterise the RCS of a target far more extensively than would be possible for similar cost and time expenditure by measurement. CST® STUDIO SUITE® provides extensive functionality to analyse and optimise the RCS of targets of all shapes and sizes. Objects of interest imported from a variety of CAD formats can be easily modified and parameterized. Different solver approaches are available to the user, depending on the size and complexity of the model, and on the desired output. Direct simulation in the time domain allows the application of realistic radar signals, visualization of time domain field interaction with the target, and direct calculation of its radar signature. For larger and more complex structures, the MLFMM and asymptotic solvers are optimized for performing fast mono- and bi-static RCS calculations of single and multiple targets (e.g. physical countermeasures), even considering realistic radar antenna source patterns. Complex material properties, for example of Radar Absorptive Material (RAM) and multi-layer coating material can be considered. This webinar will discuss all these issues using a ship-borne aircraft as an example.
