See attachement for ugly C# code... To compile it, you need to have VisualStudio2008 and install the Microsoft Chart Control library, sorry :/
EDIT : I'm going to bed now, but before some explanation for those who don't want to have a look at my ugly hacks...
I considered the data as being formated as follows :
5A A5 00 C0 <XX> D1 <data>
where <XX> has varying values around 9E, and <data> is composed of the 1440 next bytes.
Inside the data part, I considered it being grouped by 4:
byte 0 : <DIST 7:0>
byte 1 : <unknown><DIST 11:8>
byte 2 : <unknown>
byte 3 : <unknown>
I got the graph shown by plotting DIST for each degree, 0 to 359 on a polar graph. I reduced the samples to one rotation for testing, but it would be trivial to do it for all recorded rotations.
The yellowish dots are from the "NoShield" data from sparkfun, ths small reddish circle is from "shield13point87".
EDIT n+1 : better image :
