F-14 radar modes -
Pulse-Doppler Search (PDS): This mode is for basic long range detection, and is the maximum range mode of the unit. The information is displayed on the Detailed Data Display (DDD) as raw radar data in azimuth, elevation and range-rate (rate of closure). This mode does not provide absolute range to the target (only closure rate).
Range while Search (RWS): This mode yields the greatest surveillance volume, and also returns absolute range in addition to closure rate. Maximum range in this mode is slightly less than in the PDS mode. Information can be displayed on the DDD or on the Tactical Information Display (TID), although this display does not include heading, speed, or altitude information.
Track while Scan (TWS): This mode is capable of tracking 24 targets simultaneously. The radar sweeps every two seconds, stores the targets position and vectors, and estimates where the target will appear next. This mode is used only for the launch of AIM-54 missiles. This mode tracks ‘virtual’ targets while it continues to scan for new ones. However, if the target is maneuvering violently, it is possible for the radar to loose track on that target.
Pulse-Doppler Single Target Track (PDSTT): This mode provides the maximum range for an AIM-54 launch. This mode locks the radar’s attention onto a single target continuously illuminating that target. A Jam Angle Track (JAT) facility can be use to provide range, speed, and angular information on targets being protected by ECM. In this mode, the radar can be slaved to the aircraft’s electro-optical sighting unit.
Pulse Search (PS): A non-Doppler mode used for air-to-air search and ground mapping. In this mode there is no range-rate information, only range versus azimuth.
Pulse Single Target Track (PSTT): This is another non-Doppler mode, used primary during close-in combat where Doppler information is not of much value.
TL/DR: PDS has the longest range, TWS is the standard mode and PDSTT is used in high ECM environments. Seeing as multiple engagement is unnecessary, I propose the AIM-54 swap the F&F tag for 50% accuracy. The R-33 could get the same treatment in exchange for ripple fire, which hasn't made much of a difference. I'd also give the MiG-31 a decent IR missile.
