DRFM, especially by light midgets, compute incoming signal with simple filters, wich loose all information about polarisation, phase or another complicated parameters. I exactly know that radiosurveylance forces can select even SAME TYPE of transmitters, working on the same letter band and coding etc., by individual signatures of signal. So it is a matter of signal recieving and simulation accuracy. Let's give us definite numbers of this for midgets, or for Growlers, or for anything else.
And of cause small undirectional antenna can't make any rightful polarisation/phase for backsignal. Pay attention that 'mighty' HARM block A (same 1983 year) even can't to be launched on such target...
Well, I tell about old trash (because modern complexes is under secret) but you - about most modern staff. Need I add something to show advantage of ground/naval air defence better?
Now you are speaking nonsense again.
DRFM doesn't lose information about phase, it is the most basic part of pulse compression which DRFM technology are designed to counter. The directivity of the antenna have nothing to do with whether it can accurately transmit the phase of signal. And exact polarization of radio wave are very easy to detect as power reduce when there is a mismatch and there isn't that many type of polarization anyway

And don't forget about collision hazard - to launch dozens cruise missiles to point target immediatly or to laucnh dozens midgets around single plane in one time is almost impossible in practize.
They are expandable decoys, they are designed to let enemy know they are there, so that they attract the missiles from enemy force. So a decoy doesn't care that it show up on ELINT system when it uses its datalink, it already show up on ELINT system when it transmit jamming signal.
The decoys doesn't have to be launch at one time since they can fly almost 420 km, and they all have datalink guidance

ln(10) = 2.3 just saying. Which is negligible when compared to the effect of distance and RCS reduction
hocum wrote:It had deployed already, as a part of every air defence complex. F-35 can carry 24 SPEAR-EWs only with external points, so farewell stealth, and all strike capabuilities too (exept cannon and kamikadze

). In inner bays just 8. Now I am seeing clearly that SPEAR is just subsonic munition and easy target even for cannons too, nothing about 3-4M speed. And last - if every F-35 carry 4 decoys (it isn't enough even for imaginary selfdefence from single division of modern Buk - 1 Kupol + 1 2S36 + 4 9A317), just 4 places for small munitions shall left or 1 (ONE, my dear kid) for long range JSOW-kind cruise missile. Your [propaganda]advertising claims is ridiculously outnumbered again.

Do you seriously think a single F-35 will attack a whole division of various type of short and long range air defense??
Obviously not. Just like air defense can have multiple vehicle and multiple type of SAM for different tasks. The F-35 strike force will also include multiple F-35, each for different tasks. Some will have the task of releasing decoys from extended range (since SPEAR-EW have 3 times the range of SPEAR), and therefore, they won't need stealth and can carry SPEAR-EW with external weapon station. Some F-35 are attack force and stay in stealth configuration.
And you don't have to mix SPEAR-ER with JSOW, you can mix it with common SPEAR since they are the same size and with the same type of launcher, so internally, F-35 can carry 4 decoys and 4 cruise missiles. In addition, Buk doesn't outrange SPEAR or SPEAR-EW, so if we go down the road of 1 F-35 vs 1 Buk battery, there is no need to carry missile internally either
hocum wrote:How much? It is just 'my father stronger than your father', kid. Total unserious. If I can't prove something even, I use certain numbers at least. Compare with you. Of cause you want to say at least something, but this...

Firstly, JSOW is a gliding munition without engine, JSM is a cruise missile with turbojet engine that can give it 1:1 ratio of thrust/weight. Even JSOW-ER only use TJ-150 engine (the same one used on SPEAR) which has 337 lbs of thrust, which mean JSOW-ER thrust/weight is only 0.3
Secondly, JSOW is not designed to perform terminal maneuver while JSM is designed to perform maneuver to reduce the effectiveness of CIWS system. And the thin high aspect ratio wing of JSOW is also less well suited for maneuver compared to the thick short wing of JSM
Thirdly, JSOW is a glider vehicle so its speed is only the same as glider bomb. JSOW-ER also have very limited speed at around 550 km/h. By contrast, JSM speed is around Mach 0.9-0.95

Who can make them juicy targets? Firstly it must come to death zone itself. For cruise missile the same, but with fighter planes or specialized interceptors.
Coordination is a problem in war, especially when you are under attack.
There is a massive different between intercepting Orlan-10 drone which move at 110-150 km/h and cruise missile which move at Mach 0.8-0.9. And quantity also matter. Sending a whole helicopter and only intercept 1 loitering drone can hardly be called a success when something like a single C-130 can drop thousand of them
eloise wrote:So why your favorite SPEAR with turbojet (sic!) claims max.range just 140km, when gliding SDB with the same weight and similar aerodinamic claims as much as 110km range? Just adds 27%? From what drop altitudes and aircraft speeds such a range was obtained for glider? Why did such funny pictures about MALDs appear? I sure that you didn't make that picture, it was advertizing from military show.
SDB and SPEAR doesn't have the same weight, SDB is 129 kg and SDB II is 93 kg while SPEAR is 100 kg. Secondly, SDB II range against moving target is only 72 km. So about half that of SPEAR

Even in the Russia propaganda version, air defense only shoot down 70 out of 103 missiles, which mean old subsonic and non stealthy cruise missile is still 30% effective but of course, you just have to pull the 5-7% value from your behind and pretend like that the truth. Nevermind that there is no video evidence to prove the the air defense actually shot down that many missile either.

I know what you are trying to do "repeating one lie until it become accepted "

How you told earlier? 'Parroting old and debunked long ago sthereotypes'? Let's our readers will decide by themselves, who parroting old sthereotypes, uses demagogy and imitate memory losses here, when he has nothing to argue.
Firstly in the link, the detection range against Mig-21 target without interference is
The detection range against Mig-21 with jamming is:
At lower altitude, as expected, the detection range is shorter due to radar horizon limitation
Also, at low altitude, the detection with and without jamming aren't very different, but that is also as expected. Because the radar horizon cutdown the detection range to very short range, and at short range the advantage is in the radar side while at long range the advantage is in jammer side. Because radar signal have to travel out then back.
But at altitude from 500m -6000 m, there is a clear distinction.
In the without jamming they mentioned the range can get as far as 175 km
But in the with jamming case they only say the range is not less than 80 km

Do you really think that is a coincidence? or they are trying to hide the effect that jamming will have on radar at long range?

Secondly, jammers are not created equal. Without DRFM technique from the jammer side, then the pulse compression filter applied by the radar can easily reduce the jamming signal that get into the receiver by 30-40 dB

Did they use DRFM jammer in that test?. I don't think they did
Thirdly, not all target need the same level of jamming power to be protected. Mig-21 frontal RCS can be as high as 8 m2 so compared to a VLO aircraft such as F-35, then the jamming power needed to protect the Mig-21 needed to be 8000 times more powerful
