Sionna Spherical Coordinate System and Boresight Convention

[Petimothee]

Hello,

What is the convention for the spherical coordinate system used in Sionna? I would just like to verify this, ideally with a diagram of the convention, to make sure I understand. Does it follow standard convention, as shown below?

Also, the default boresight of the antenna is the +x direction, not the +z?
Thanks!

Hi @Petimothee,

I would look here: https://nvlabs.github.io/sionna/rt/em_primer.html
This is equivalent to what is defined in the 3GPP 38.901 specs.
