Using the Radar on F-14A
F-14A carries the AWG-9 radar, the most powerful radar of its time. The radar was desgined specifically for fleet defense, and when used with the AIM-54 Phoenix missiles, it can engage up to 6 enemy bombers at once at range of almost 100 miles. There is no raw radar display in the pilot's cockpit, instead, there is TID (Tactical Information Display), which shows not only the target detected by the radar, but also all the targets detected by nearby airborne early warning aircraft.
There are three selectable modes available: Search (Range-While Scan, or RWS), Track-While-Scan (TWS), and Air Combat (Vertical Scan Lock-on, or VSL) modes. Single Target Track (STT) mode is entered by the radar system when a target track is established. All radar modes display the same top-down, birds-eye view of the battlespace in front of the aircraft, up to 400 miles display range.
Search Mode
Search mode has the widest search volume and fastest search time, but only shows minimum information regarding targets. Target can be designated using the "Next/Previous radar target" keys, and the "Acquire selected target" key can be used to transition to STT mode unless AIM-54 missile is currently selected, in which case the radar will switch to TWS mode instead.
Track-While-Scan (TWS) Mode
TWS mode displays additional information about the currently selected target and is used for engaging multiple targets simultaneously with the AIM-54 missiles. Radar in TWS mode scans slightly smaller volume than in Search mode, and radar elevation is automatically centered on the currently highlighted target. Different targets can be selected using the "Next/Previous radar target" keys. When the AIM-54 is selected, up to 6 targets may be designated using the "Acquire selected target" key. When the first target is designated, a number "1" appears next to the target. And each time a different target is designated (by hitting the "Next/Previous radar target" to go to next target and then hitting the "Acquire selected target" again), next number in sequence is assigned ("2", "3", "4", etc), up to the number of AIM-54 currently carried. When an AIM-54 is fired, it automatically aims to the next target (designated "1") and the sequence is cycled down by one (so "2" now becomes "1", "3" becomes "2", etc) for the next missile, allowing the pilot to fire all 6 missiles at 6 different targets at once. When other weapons are selected, the "Acquire selected target" key switches to STT mode instead.
Single Target Track (STT) Mode
STT mode displays the all the same information as the TWS and is used to guide the AIM-7 radar-guided missiles. While in this mode, the radar does not search for any new targets, but new targets can still show up on TID if detected by the airborne early warning aircraft.
Auto Acquisition Mode
Radar in Auto Acquisition mode scans straight ahead and vertically from 0 to 40 deg above the boresight line. It automatically locks on to the first target it encounters in its vertical search arc, and switches to STT mode.
