Currently the quality of generated pattern signal.
In polytone pattern mode your got two carriers. the first with level 0 dB the second ( depends from the distance step ) -13.. - 22dB
I tried different mode ( polytone relative ditone) see screenshots.
Can I get more suppression for the mirrors ?

Yes you get a complete supression by moving the SPECTRAN V6 center frequency e.g. in your case from 320MHz to 340MHz and by using SPAN="1/2" instead of "FULL" or/and using higher sample rates (122MHz instead of 92MHz):
