LesmoR Posted Tuesday at 11:11 AM Posted Tuesday at 11:11 AM Our Viper operates with AN/ALR-56M RWR, which derives from AN/ALR-56C on F-15s. As part of a SEAD platform, how capable is the AN/ALR-56M? (e.g. Effective Range? Band Coverage?) afaik The AN/ALR-56M has 360 azimuth coverage but 45degree elevation limitation, E-J band coverage and uncertain C,D band detection ability, does that mean some emitters operating on these bands will not trigger the RWR? Also, the TEWS on F-15 is able to identify whether the radar threat is above or below the aircraft and inform the pilot through voice warning, does that apply to the Viper?
_Hoss Posted Tuesday at 03:27 PM Posted Tuesday at 03:27 PM (edited) In the AN/ALR-67 in the Hornet, there is what's called the Threat Library memory card. Each target tracking and search RADARS, have their own unique PRT and PW signal characteristics. Or it's own Finger Print that distinguish it from other systems. Most RWR receiver's filter or band pass signals between .5 to 18 GHZ, where your AN/ALQ-126 Deception Repeaters in the Hornet only pass signals between 2 to 18 GHZ. It will not respond to Search RADARS. The cockpit display will display icons of specific threats that it's Threat Library recognizes. The ones it can't, it shows as UNK, unknown. If you know your threat RADAR symbols you will know if you are looking at a Search RADAR, or Target Tracking RADAR, both Surface and Airbourne. And your system (ALQ-126) will only transmit when you are receiving a specified signal strength. So as you draw closer the signal strength increases, to the level needed to trip a signal discrete in the system to fire the transmitter. It also does the reciprocal as the signal strength decreases.... I.e. range. The Library is programmable to update to new theater threats. But we have to take into account whether or not the module maker actually understands these variables. After all it is a game, not real life. Edited Tuesday at 03:29 PM by _Hoss Sempre Fortis
