Berry,
Good question
. But prop noise wouldn't restrict radar, mast obstruction would.
It does bring up another point though ... In my original post I mentioned that there was a 21'st entry found, only with BearingMin/Max info. Perhaps this is the heading restriction the program supposed to read and compare it with other parameter's. I dunno.
I think their intention was to simulate the actual beam width.
The SJ H.P. beam width:
Horizontal 9 degrees.
Vertical 29 degrees.
This coincides somewhat with the ElevationMin=357.5 Max=30, SweepArc=9.
Elevation Min/Max numbers for even the sonar show 0 and 360, which makes sense, but not observed as a bug since it covered 360 degree's of the sub heading.
Radar # 16,17, and 18 have bearing restrictions, which, if I'm right, means that three boat classes had mast assembies that blocked radar coverage, not because of prop noise. Both the SJ and I-SJ was located on the front on the mast assembly so as it rotated through, say between 150-210, it might have stopped radiating because the lobe would interfere with the SD (jamming) or reflected energy could "burn" the watch crew!!
. The SJ on the earlier boats might not have had a problem. I'd have to physically look.
It's really a mystery about what's going on.
