76 Radar Warning Receivers<br />
RADAR WARNING<br />
RECEIVERS<br />
Aircraft, ships, and ground stations broadcast radar signals everywhere searching<br />
for adversaries. Naturally, modern combat aircraft carry receivers designed to<br />
detect these emissions and warn pilots. Although Eastern and Western aircraft<br />
designers take slightly different approaches to the common problem, all radar<br />
warning receivers (RWRs) share some common aspects.<br />
First, RWR equipment is passive, meaning it emits no signals of its own. It<br />
“listens” for the emissions from other transmitters, indicating the type of<br />
transmitter, the bearing to the transmitter, and if the emitter has locked onto the<br />
aircraft. RWR gear, however, does not indicate the range to the emitter.<br />
hRWR equipment does not indicate the range to the transmitter.<br />

The A-10 and F-15 radar warning receivers look slightly<br />
different, but operate virtually the same. In either<br />
aircraft, the center of the RWR represents your aircraft.<br />
The circular display represents the bearing around the<br />
plane; the top of the display indicates bearing 0 (directly<br />
ahead) while the bottom denotes bearing 180 (directly<br />
behind). The position of icons around the circle,<br />
therefore, indicates the bearing to the emitter.<br />

A-10 Radar Warning Receiver<br />
The screen presents icons in two<br />
rings. The rings indicate the relative threat presented by the<br />
radar sources, but do not indicate the range to the emitters.<br />
The outer ring shows radars in search mode; the inner ring<br />
displays radars that have locked onto your aircraft. A tone also<br />
sounds, providing an audible alarm when radar locks onto<br />
your aircraft. Icons representing incoming radar-guided<br />
missiles will flash.<br />
In the A-10, search and launch warnings are also indicated on the warning panel.<br />
Radar emitters are abundant on the modern battlefield. The RWR equipment can<br />
quickly become confusing, distracting, and even overwhelming as it displays the<br />
wide variety of contacts it detects. Consequently, the RWR supports three<br />
“declutter” levels:<br />
• Show All: Shows all detected radar sources.<br />
• Show Only Lock: Shows only radars locked onto your aircraft.<br />
• Show Only Launch: Shows only radar-guided missiles tracking your aircraft.
