If you read the following article, it does have missile detection and tracking already. With the newer versions of tail warning radar, you can detect, and identify what type of fighter is tracking you, and this will tell you the kind of aircraft. Rarely do two aircraft have the same radar but might have the same frequency band. In fact, you don't really care what kind of plane is following you, you just want to know if a missile has been fired, what kind and from which direction and is it above you, or below. With that information you should be able to avoid the missile. www.northropgrumman.com/capabilities/anaaq37f35/pages/default.aspxNot talking about the same thing oldpop ... I'm on missile targeting (offensive) and you're on threat detection (defensive). MAWS (missile approach warning system) is already wide in use... F-15/16/18/A-10 and the lot. The whole idea is very simple: Search, acquisition and track then engage. When we moved from the APQ-72 Single target track system on the F4B to the F4J’s AWG-10 multiple target track system it was a quantum leap. Now the new planar array could scan, search, acquire multiple targets, then track multiple targets. The pilot could then decide what his tactics will be, make the decision, and then engage. You cannot separate a missile approach warning system from a missile targeting system. They must work together whether it is an aircraft or a ship. We have always had tail warning radars in our aircraft, however they have been dramatically improved over time. Now we can see 360 degrees, then engage but the whole process is the same. Search, acquire, track and engage. All the electronics including optics are integrated through the central computer. The radios, INS, doppler navigation, GPS, fire control system, air data systems everything. They all work together. Here it is: If you examine the quoted information above, you will see: Search, acquisition and track functionality. While they might change terminology and they will, it still performs those same three functions.

While they might change terminology and they will, it still performs those same three functions. traditional IRST doesn't provide ranging/velocity info. The pilot can use it to cue missile like it is on the Flankers/Fulcrums for years, but since there is no range, possible missile pk is a pilot guesstimate. At least from public source we don't see the DAS can range yet. was hoping in future it could.

The answer is in this quote, right here: F-35 DAS and APG-81 radar demonstrate ability to detect, track, target ballistic missiles Northrop Grumman Corporation recently demonstrated the ballistic missile detection, tracking and targeting capabilities of the company's AN/AAQ-37 distributed aperture system (DAS) and AN/APG-81 active electronically scanned array (AESA) radar, both of which are featured on the F-35 Joint Strike Fighter (JSF) aircraft. Northrop Grumman's DAS and APG-81 autonomously detected, tracked and targeted multiple, simultaneous ballistic rockets. The DAS autonomously detected all five rockets, launched in rapid succession, and tracked them from initial launch well past the second stage burnout. If the DAS is tracking, as it says, then it has azimuth, range and altitude of the target, it can't track without those three components. Here is a good link: foxtrotalpha.jalopnik.com/infrared-search-and-track-systems-and-the-future-of-the-1691441747Here is another good article on the basics of IRST - defenseissues.net/2015/06/16/airborne-irst-properties-and-performance/

The AESA could provide ranging info. Another potential solution is to pair the DAS camera with a laser ranging device. But they will likely have to work out effects on stealth and fuselage space. .... Apparently it is also a hot topic for fighter enthusiasts - aka whether the DAS have independent ranging ability. aaannd it later comes to whether the DAS has a laser rangefinder and becomes a mess, as expected:D www.f-16.net/forum/viewtopic.php?f=55&t=53816Especially this post I think is rather convincing www.f-16.net/forum/viewtopic.php?f=55&t=53816&start=42You can look up more on the subject. Lemme know of any new findings.

Lemme know of any new findings. I added another link to my previous post, did you see it? One more item to keep in mind. Besides Azimuth of the target, range and height, you also need range rate. Is the target closing, moving away or running parallel. You gather this from the doppler effect of the radar. The initial radars for airborne intercept did not have that capability, the ability to interpret the change in frequency due to the doppler effect. later versions do and did have this capability. If you need more information, I can either explain or find a piece to do that. Keep in mind also, we do not know all the capability of any integrated system due to security. All of us had to sign off that we would not reveal anything we learned. So, Don't assume any article is complete, because it isn't.
