I have to go, so I'll make this quick:
1. Anytime you use SAR, and illuminate a SAM/AAA site, it sees the full emition, not some "fleeting EM source". If the SAM/AAA is well camofloged, then the SAR may not even pick it up. If it does pick it up, it may not be able to recognise it. In all these cases, the combo of the better SAR of the F-35, the EOTS, and the DAS makes unexpected GBAD less likely.
1. Your assuming the SAM/AAA site has sophisticated ESM equipment, not necessarily so.
2.The EM source is fleeting because its only emitting while the scan is taking place, once the scan is complete the source goes cold and thus it is "fleeting". Emission power has nothing to do with it.
3.
If the GBAD detects the SAR scan all it has s a threat bearing, it wont be able to geo locate the source without multiple bearings. Thus this information is useless to anyone without range information, including the battery being interrogated.
4.Any operational high end SAM threat (ala S300 PMU) will have very large TEL's and also large (and moving) PESA antennas deployed (ala the 10m high Big Bird). While operating these systems are not easily camouflaged. Any tactical SAM's or AAA which can be camouflaged more effectively are likely to be out of range as the F-22A would most likely be penetrating at high altitude.
Below are pictures of a Deployed S-300 PMU battery, you think 3rd gen AESA generated SAR is going to have trouble spotting that?
5. EO DAS is only going to be used for targeting GBAD if the threat is VERY close and under any cloud cover (much more dangerous than using SAR). EOTS will enable the F-35A to engage the threat from altitude
only if weather permits. If not (like most of the time during OAF) then the F-35A will be using SAR for targeting.
2. As far as the DAS being virtually the same as MAWS, the DAS is much better. The DAS provides not only launch and tracking but also IIR imagery of all air and ground targets. It enables over the shoulder AIM shots without having to use the HMD. Check
this pdf for some nice SAR and DAS imagery from the F-35.
5. Mate you need to read what your quoting, you've basically repeated what I said and drew a different conclusion. I never said the MAWS was "virtually the same as EO DAS" I said it was developed from the F-22A's MAWS. As i stated earlier the major benefits are in the A2A regime (not relevant to this discussion) and the ability to display IR imagery in the HMD. If the GBAD site is close enough to be targeted through the EO DAS then the platform is probably close enough to be compromised by all and sundry at low level. If either platform is engaged by a missile both the MAWS and EO DAS will provide the driver with threat baring information (what they're both designed for), the only difference is the Lightning driver will be able to view the threat with IIR. Pretty small advantage in the circumstance i would say considering both systems will communicate the same information.
3. All the features for the F-35 are paid for and WILL happen. Upgrades for the F-22 are NOT PAID for and have been trimmed back for even the ones that they have planned on.
6. That may be true, but if you want to follow that line of logic we shouldn't even be discussing this because the F-22A exists in the real world and the F-35A is a test and development program (ok and some LRIP). One exists and the other one doesn't. Thats why I prefer to discuss what is reasonably likely, as I'm sure the F-35A will see squadron service, but we cant be certain can we?
Thus your stacking the cards in your favor, by comparing the F-35A of 2015~2020 and the F-22A of 2009.
4. The difference between the F-22 and F-35's RCS, when compared to legacy systems, is very small.
7. But were not comparing other platforms, we're comparing these two, thus comparing performance of legacy platforms is irrelevant.
