Basically -yes - but a good starting point would be quadrants - +-45deg front, right side, rear, left side.

My point about averaging still stands though.


If say the sides have one large spike, averaging the RCS still inflates the apparent RCS overall - when in 88 of  the 90 degrees, the RCS is in fact super low.  You might even quote the 88 degrees RCS value as the typical "golfball", but at some critical angle its more like a beachball, or even a whale.


Pogosyan's article suggests F-22 & F-35 both have RCS of 0.3 m (no direction specified), in order to claim that the Su-57 target of 0.3 m puts it in the same class. It doesn't.
