To accompany the CST Studio Suite Student Edition, we have prepared some examples, which are typical of the type of textbook problems you may encounter during your studies of electromagnetic theory or other related courses. With this free edition you have – bar some restrictions – access to our powerful visualization engine and some of the most advanced solvers of CST Studio Suite. The CST Studio Suite Student Edition introduces you to the world of electromagnetic simulation, making Maxwell’s equations easier to understand than ever.

So let us get to know you, and we will figure out a world-class software solution unique to your needs and couple it with excellent pricing and reliable support. They feature extensive textual and graphical explanation, videos, and input deck downloads.ĬAE is essential to modern engineering, but it’s an ever-changing landscape of infinite possibilities.

This simulation can provide valuable information to clarify which real world objects cause images suitable for high accuracy identification in the SAR images.There are plenty of tutorials of example problems that are available to you at the DS Resource Center. Range compression, range cell migration correction (RCMC), and azimuth compression are applied in time domain to obtain the final SAR image.

Hilbert transform is applied to convert the real signal to complex data with phase information. Exported data from CST is arranged into a 2-d matrix of axis range and azimuth. The time domain solver in CST is based on the solution of differential form of Maxwells equations. This is analogous to an array antenna and is synthesized to create a long aperture for SAR processing. Defining mesh and other appropriate settings reflected wave is measured at several distant points within a line parallel to the viewing direction. Within CST Microwave Studio a replica of TerraSAR-X chirp signal is incident upon a modeled Corner Reflector (CR) whose design and material properties are identical to that of the real one. Raw data is later focused in MATLAB using range-doppler algorithm. This paper presents the use of a general purpose electromagnetic simulator, CST, to simulate realistic synthetic aperture radar (SAR) raw data of three-dimensional objects.
