SCS has said that detailed radar modelling isn't something they are particularly interested in including in detail, for a number of very good and justifiable reasons that relate to simulation and programming complexity and, most importantly, gameplay, but what you have suggested is a really good idea.
However, it would require a major restructuring of the database aside from significant changes to the interface and engine... so it's not likely to happen. Sorry.
But after all, they are called SONAlysis, and not RADAlysis.

:rotfl:
So, I'll give them a solid pass on this one...
