Hi, I was playing the Lock-On simulation, and set-up a test BVR scenario of 1 F-15C vs. 4 Mig-29S about some 50 km. apart and flying at each other. I play as the F-15, computer plays the Migs. As the fight is on, both I and computer switch radars, BVR mode on, also activate ECMs, I see stack coloumns of enemy jammers in the screen and we continue to close... I am able to burn through at almost 5-10 kms - very close - almost at WVR range.

The other time around I try 1 on 1. With only 1 jammer in front of me, this time I burn through much far then when there was 4. So I got surprised.

Is there such a thing as numbers of jammers jamming a radar increase, the burn through range will decrease in real life? I.e do the intensity of jamming waves stack up and go high even though they operate from seperate planes?

I know this is a game - simulation, but they try to make it realistic to a certain degree, so that got me interested. Sorry if it is something ridicilous. As civilian enhusiasts we can only know the info available out on open sources. THank you for your help and time.

Note: I also noted the AMRAAM is much harder to make a hit in HOJ mode when there are multiple jammers ahead.

probably not going to get alot of answers on this one..... ECM is a big Big No No

to talk about

I can imagine that. But I am not asking about a specific suit's performance... This is a general question about jamming phenomena.

But still, you're asking for info/elaboration on a topic that while may be part of a video game, cannot be discussed by professionals in this field in the real world.

I understand ok, I am sorry if I caused some mistrust by acting over-eager for critic info. I just wondered about what I saw is actualy in real life phenomena or not thats all...

It's a great community. You can get answers there.

This can easily be discussed at a basic level and theory so long as we avoid specifics.

Noise jammers blot out returns by simply overpowering them with typically non-coherent noise. More jammers would theoretically improve their effectiveness.

Technique or deception jammers (of which self-protection jammers tend to be since they require less power and size and can therefore be carried by fighters) send back a carefully crafted version of the original signal to mislead the radar or it's operator. The timing of such signals is critical and is difficult to coordinate amongst multiple jammers. Not to mention their "techniques" can step on each other and do more harm than good.

All of the above can be found in any basic EW textbook such as Dave Adamy's "EW 101"

Thanks a lot Roscoe, a simle and very informative answer. With my limited knowledge on ECM thing, I tought the case was that also, thats why I was surprised with the sim.

Anyway I think its the problem with sim, that sim is problematic in some areas anyway, it overrates Russian aircrafts and downgrades US aircrafts performances to some degree. Now this thing. I think it treats all jamming as noise jamming.

Do ECMs in a formation stack up to overpower enemy radar?
