80 Radar Warning Receivers<br />

processing power, the RWS not only detects radar, but also indicates the bearing<br />

to the transmitter and the type of radar detected. A totally passive system, it<br />

merely listens for other’s emissions. This system is used in a variety of Russian<br />

aircraft including the MiG-29 Fulcrum , MiG-31 Foxhound, and Mi24P Hind.<br />

The ten lights surrounding the MiG-21 picture illuminate to indicate the bearing to<br />

the transmitter. A flashing light indicates your aircraft is being painted occasionally<br />

by the emitter. A solid light indicates that a transmitter is tracking your aircraft. A<br />

red light surrounding the silhouette indicates a lock onto your aircraft. The six lights<br />

along the bottom of the RWS correspond, from left to right, to five categories of<br />

radar signals:<br />

• Airborne radar<br />

• Short-ranged SAM<br />

• Medium-ranged SAM<br />

• Long-ranged SAM<br />

• Early warning radar<br />

• AWACS<br />

Indicators<br />

All Russian aircraft are equipped with an Identification Friend or Foe (IFF) system,<br />

allowing the RWS to distinguish between friendly and hostile radar sources. This<br />

system also replies to friendly emitters, alerting them that you’re not a hostile<br />

target.<br />

Missile Launch Warning System<br />

The infrared MLWS detects the hot emissions produced by incoming missiles. A<br />

totally passive system, it watches for the type of heat produced by solid-propellant<br />

rocket motors. Its effective range varies depending on the intensity of the heat<br />

emission, but can generally spot inbound missiles up to 15 km away.<br />

When the MLWS detects an inbound missile, the GECR symbol (meaning<br />

“launch” in Russian) illuminates and produces a warning beep at 2 Hz for five<br />

seconds. The MLS light also illuminates. After five seconds the audio alarm<br />

silences, but the warning light remains on until the system loses contact with the<br />

missile.
