[We were] cleared visual approach into FTY. First Officer said FTY airport straight ahead 2 miles away. I looked at the airport and then started to enter a left downwind heading west for landing runway east. I then realized that I was entering left down wind to Dobbins AFB. I then proceeded to turn south to FTY. Altitude was 3;000 MSL; ATL Control contacted us and said don't go below 3;000 MSL. Our GPWS activated saying terrain; pull up; pull up? We were in visual conditions and had no terrain or obstacles in our flight path? The highest obstacle in the area was 1;800 FT MSL. Not sure why GPWS activated; but I should've confirmed with ATL ATC of correct airport and scaled down INAV mile view to confirm.
A Falcon 2000 Captain; cleared for a visual approach; initially mistook Dobbins AFB for his destination airport and set up for a downwind. When he later altered course to correct the GPWS issued an unexplained Terrain GPWS warning.
