And therefore should be deployed in a directional manner..... Or are they radiated out in a ark.... I really don't know anything about them… I guess I should wiki at it… But I would prefer to just ask mom… Because I'm intellectually lazy…

I really don't know anything about them… can jammers act against more than one unit at a time… I guess I should wiki at it… But I would prefer to just ask mom… Because I'm intellectually lazy…

Status: offline 		EW 101: A First Course in Electronic Warfare, by David Adamy and published by Artech House Radar Library, is an excellent resource for a basic understanding of electronic warfare principles.

It was made available for free in multiple parts several years ago in issues of the Journal of Electronic Defense, by the Association of Old Crows, but that resource is now by paid subscription.

Status: offline 		I've made a scenario with SA-20b (radars Cheese Board 96L6E and Tombstone 30N6E) against a group of F/A-18F's and EA-18G.
- jamming was particularly effective at the angle of roughly +-20° from the axis of jammer, somewhat less effective at higher angles
- if the SAM considered targets as unknown, it could be quite easily jammed (at distances mentioned below). If it considered targets as hostile (or was set to engage unidentified targets), it could maintain lock much better (I believe this is caused by Tombstone switching to illumination mode).
- range of jamming greatly mattered. At longer ranges, jamming seemed to be ineffective. Tombstone could reliably illuminate and guide missile to F/A-18 at 74nm and below. At 40nm it started to have difficulty in maintaining lock, it could still engage, but missiles often self-destructed because of long breaks during illumination and only a small percent reached targets. Finally at 25-30nm its guidance was completely unusable, it even lost all targets and couldn't find any until burn-through, which occured at 4nm.

What surprised me was inefficiency of jamming at greater distances, where jamming-to-signal ratio is higher and jammers should have no trouble with operation. Based on this behavior it seems better to hide under radar horizont to completely avoid detection and not use jamming at longer distances, since it can be detected with ESM.

I don't think the modelling of EW in CMANO is very sophisticated. I'm sure it will improve with time.

EA-6/EF-111 tracks are approximately 40-50nm from downtown Baghdad.

Nerdy indeed and obvious a lot of thought has gone into it. It is still, however, just a game.

Status: offline 		Really impressive.... Thank you guys... So much to learn..... The modeling is remarkable..... Now I need to know how to apply some of this.....

Rudd... The maps are reall interesting..... I'm going to save them.....

Doesn't it seem wrong that the US Air Force doesn't have any offense EW jammer aircraft organically in their asset mix.... That really doesn't sit right with me it just seems wrong… i'm all for jointness and maximizing the economy and efficiency of our assets and platforms jointly across our services..... However I think this issue goes too far...... They should get that big big ass B-52 jammer strike Boeing... that thing is Godzilla awesome..... truly Star Wars....
