Hi. I'm trying to collect some SAR datas for my school project. I have an 25GHz dual-polarized antenna for transmitter and a dipole antenna for reciever. I want to collect data every lambda/2 steps then I will export port signals and use them in MATLAB.

However, I need to collect 116 data for this scenario and every step has nearly 50M mesh size. So I need some advice to reduce mesh size or an easy way to simulate SAR.

Best regards.
