the DRFM, for what do we need them, as Jammers or what??

This devise can also be used for spying puposes . Like tracking audio frequency . We can make this device locally . All you need is xylinx spartan 3 FPGA with necessory coding to prototype it. You can compleetely paralize enemy's aircraft by transmitting a virus into its digital radar signal processor and this is the reason why some of the most advanced aircrafts like F-22 or Stealth F-117 are so vonreble to deadly radar waves which they can recieve. A UAV is more exposed to such kind of electronic warefare , you can compleetely paralize it.A digital radio-frequency memory (DRFM) is an electronic countermeasures device that samples and quantizes (analog to digital conversion) an incoming radar signal and produces (digital to analog conversion) a jamming signal from the sampled radar signal.

Digital signal processing , Quantization . Awesome subjects .
I m doing Computer Engineering and working on a simillar kind of project. A Jamming device which can jam the radars by corrupting the incoming and reflected signal .

As far as i recall, the offensive electronic measure usually composes of very strong interference at the same frequency of target, due to complex frequency hopping measures by modern radars it is not that easy to succeed in damaging a system this way. The more spectrum a jamming device needs to interfere with the less power at each frequency within the spectrum it shall be able to throw at the target device. This limits the chance of damaging the target system though it shall still degrade the performance of the target system.
If the frequency pattern of the radar can be predicted then the objective is to concentrate the energy at those frequencies and bombard the target system with enough energy to take the target system beyond its limits in the receive path and desensitize it or damage it permanently this way.
I honestly did not know one can attack a radar system with a virus in combat...how would the target radar be made to receive and execute a software routine which damages its DSP?
The digital signal processor may be corrupted with a virus but how would it enter the software subsystem?
UAV receives its instructions via a remote station so yes it is much easier to disrupt its communication but to damage (not disrupt) a radar/electronic suite of an advanced combat aircraft is quite a tricky thing to achieve!
Just curious, even though i am quite out of touch but still an engineer.
Wikipedia said:Suter is a military computer program developed by BAE Systems that attacks computer networks and communications systems belonging to an enemy. Development of the program has been managed by Big Safari, a secret unit of the United States Air Force. It is specialised to interfere with the computers of integrated air defence systems.[1]
Three generations of Suter have been developed. Suter 1 allows its operators to monitor what enemy radar operators can see. Suter 2 lets them take control of the enemy's networks and direct their sensors. Suter 3, tested in summer 2006, enables the invasion of links to time-critical targets such as battlefield ballistic missile launchers or mobile surface-to-air missile launchers.
The program has been tested with aircraft such as the EC-130, RC-135, and F-16CJ.[1] It has been used in Iraq and Afghanistan since 2006.[2][3]
U.S. Air Force officials have speculated that a technology similar to Suter was used by the Israeli Air Force to thwart Syrian radars and sneak into their airspace undetected in Operation Orchard on September 6, 2007. The evasion of air defence radar was otherwise unlikely because the F-15s and F-16s used by the IAF were not equipped with stealth technology.[2][4]
^^^^I thought this is an F-16 discussion thread
If they can do it to a ground-based radar targeting system, they can probably do it to an airborne system i.e. combat aircraft and AEW/C radars.
I have heard that something like 76 planes have been shot down by F16s with out any losses in air to air combat with the exception of once when one pakistan F16 shot down by another Pakistan F16 by a sparrow missle in an engagement with Afgan in the 80s. Can any one verfiy this...
