For angles, you can just increment them past 360.0. In
the conversion to Cartesian coordinates angles pass
through trig functions which are periodic, so they
produce the same value for an angle of 430.0 as they do
If your range values decrease then increase, then your
sampling has a fold and is not really a grid. I'd say
draw a rough picture of your sample locations and see
if there isn't something wrong with the assumption of
range values decreasing then increasing.
