|This is a good photo of the APQ-116
fire control radar in the A-7 Corsair. The APQ-116 had many useful
modes. If I can remember correctly, they were, Weather, Fire
Control, Bomb Direct, Ground Map, Terrain Following and Terrain Avoidance
and Walleye Modes. By modern standards, this system was antique.
It has a black and white display and a limited range and resolution.
The newer radars found on the F-14 Tomcat, the AUG-9, is much more sophisticated
using a flat plate antenna and capability of tracking as many as six targets
For those that don't know, RADAR stands
for Radio Detection and Ranging.
