From a visually standpoint, the (F-4J) APG-59 radar of the AWG-10 ( and APG-60/61 of the AWG-11/12 of the F-4K/M)
was different only that in the doppler lookdown mode the presentation was in Velocity vs Azimuth
Similar to the "Velocity Search " modes of the Lock On F-15 etc.
The other modes were basically the same of what we have already.
APG-59 was still very limited, with the doppler function more a search mode and not really "shoot down", especially not with AIM-7E series missiles.
The F-4S had the improved AWG-10B with an upgraded APG-59 which was said to be much improved over the original version.
AWG stands for Aerial Weapon Group which descripes the complete system consisting of several sub-groups like the radar, missile firing computers, the optical sight etc.
Now going back on topic...

followed by Omani super Hunter and the F-8E and the A-4A ...
