reported earlier A/G Radar EXP modes forward blanking incorrect for APG-73

[Harker]

Currently, with the A/G radar, when operating in EXP modes that use DBS/SAR, the picture for +/- 5 degrees in front of the nose of the aircraft is completely blanked out.

While this is correct for the older APG-65, based on documentation I've found, the APG-73 should have that part filled with RBM (Real Beam Mapping), like it is currently implemented in the F-16C and the JF-17.

"For navigation: wide-field-of- view, 8:1 DBS, with real beam mapping filling the ±5° forward blind sector."
