Certainly sounds difficult--we may find nobody is doing it.
Long as I've posed a difficult task, let me make it tougher: I'd like to
see a system that could provide a computerized waterfall display (angle
displayed on  vertical axis, with signal strength displayed on the
horizontal
axis).  That should sort out your second comment.
