Electronic War in BMS

Gente de mal vivir...

Podrìas indicarme donde puedo obtener información de como està simulada la guerra electrónica en el BMS? principalmente si están simulados aviones como el EA6 Prowler, o el EF18G Growler?

Parcialmente, por lo menos en antiguos Falcon poniendo en un paquete un avión de guerra eléctrónica tipo EA6B o EF111 inhibia los lanzamientos a los miembros de ese paquete.

Pero en la actualidad en BMS como no los utilizamos si te soy sincero no se en que estado está. Me ha picado la curiosidad lo investigo y te cuento si no lo hace otro antes.

Un saludo

Pues sí, ha cambiado en BMS:

Maybe some of you noticed but the ECM coverage of ecm support flights has been vastly improved

in short

1) the ecm flight provides an area coverage around its position
2) the ecm flight does not need to be in your package to protect you but any friendly flight in its area will be covered -as long as it is between jamming waypoints-

The EF111 and EA6B now covers an area of xx NM around them.

the way this is computed is quite tricky.

Imagine an Aircraft which has a nominal detection range of X.

First, the code computes what is the range between this aircraft and the Jamming aircraft, let's say jamming Range.

if jammingRange > X*2.25

then the radar of the aircraft is not impacted.

if the jammingRange < X*2.25, then the radar range will be reduced by the ratio of its normal range and the jammer's range to the radar to the power of two

so in short, the closest the aircraft will be to the jamming aircraft, the more "jammed" it will be and if you fly very close from the EF111, you will be detected only at a very close distance.

the Far away you are from the jamming aircraft, the less protected you will be.

Indeed, the jammer will be more efficient on short nominal range radars than long nominal range radars

this is independant from the fact that the jamming aircraft is in your package or not.

so yes now EF11 and EA6B are of a vital importance in campaign

Pues es mas o menos lo que he hecho yo

;) ;) ;)

Pues ahora ve y explícaselo a los de ED para que lo implemente y te ahorren el trabajo :lol:

Ja te digo.

Bueno, los del Viggen han puesto ECMs interesantes en los barcos.

Esto es del RP5, basicamente de cuando Falcon dejó de ser el Falcon 4.0 de Microprose, es viejo pero es la base de lo que hay ahora:

One of the major components in an air campaign
is the usage of tactical jamming assets, such as
stand-off jammers, to disrupt the enemy’s integrated
air defense system. The usage of tactical stand-
off jammers will prevent enemy IADS assets such as
EW radars and SAM radars, from detecting your
own strike packages, and engaging them. This as
pect was never implemented in Falcon 4, and
constitutes one of the most glaring omissions
from an otherwise well designed air campaign engine.
Stand-off jamming targets the communication links, as well as detection and early warning radars in
an air defense environment. Most modern SAM fire c
ontrol systems require some amount of initial
targeting information in order to initiate a fire
control solution that will lead to an engagement of the
enemy airplanes. Enemy interceptors will also rely
on targeting information from early warning radar
sites, so that they can be vector
ed to the correct location to intercept the intruders. Stand-off jammers
targets the early warning radars that supply the in
formation to the SAM batteries and interceptors, and
forces them to detect the target
s using their ow
n onboard sensors.
SOJs are primarily noise jammers, putting out white no
ise at the frequency of the victim radars. For a
radar to be susceptible to jamming, the jamming signal
must be close to the victim's radar frequency.
The distance that it needs to be at depends on the ant
enna design of the victim's radar, as well as its
characteristics. Most modern radar
receivers have some form of AG
C (automatic gain control) logic
implemented in their radar receiver. Radar re
turns are very much weaker than the radar
transmissions, and hence radar receivers are designed
to be very sensitive so they can listen out for
the echoes. If the returning RF pulse is of a high si
gnal strength, it can potentially saturate or burn out
the receiver, due to the receiver’s
high sensitivity. The gain control l
ogic will reduce t
he receiver gain,
so that the returning RF pulses do not saturate or burn out the receiver. If there is a legitimate target
return, and the receiver gain has been reduced, the
receiver may no longer be able to detect the
legitimate target return simply because the sig
nal strength of the target
is below the detectable
threshold. Now, if there is a legitimate target retu
rn, but there is a lot of RF white noise, the signal
strength of the white noise may be higher than that
of the target return. Under such circumstances,
the target can no longer be detected since its re
turn has been “drowned out” by the background
noise.
What an SOJ does is to achieve these effects. It in
troduces white noise to t
he receivers of the victim
radar. This “drowns out” legitimate
target returns, unless the target is sufficiently close to the victim
radar such that its returns have a higher signal
strength than the white noise. The high signal strength
of the white noise will also cause t
he victim radar receiver
to reduce its gain, thus making it even less
sensitive to weak target returns. The detection ra
nge of the victim radar will be reduced. It is possible
to jam a GCI radar through its side lobe, in addition to jamming it through its main lobe.
Stand-off jammers are now implemented in the Realism Patch. If an ECM squadron is available in TE,
such as the EA-6B, the SOJ flights can be assig
ned to provide stand-off jamming protection to other
flights in the same package as
the jammers. The SOJ has been implemented in 2D and 3D combat,
and its effectiveness is dependent on
the range at which the SOJ is flyi
ng from its victim radar. If ECM
squadrons are available in ca
mpaign, the ATO engine will ta
sk them for jamming missions.
If the SOJ is within 1.5 times the nominal 2D radar range of a radar equipped SAM unit, a radar
equipped objective, or an AWACS, the detection rang
e of the SAM unit’s 2D radar is reduced by a
power of 2 on the square of its
detection range. The mathematical relationship is as follows:
(Effective Victim’s Radar Range)
2
= (Victim’s Radar Range)
2

((Jammer’s Range from Victim)
2
/ (Victim’s Radar Range

1.5)
2
)
2
This is best illustrated by some examples. Assumi
ng that the radar has a detection range of 200nm..
1. If the SOJ is flying at a range of 300nm. or
more from the radar, the radar’s range is
unaffected.
2. If the SOJ is flying at a range of 290nm. fr
om the radar, the radar’s range is 187nm..
3. If the SOJ is flying at a range of 200nm. fr
om the radar, the radar’s range is 89nm..
4. If the SOJ is flying at a range of 100nm. fr
om the radar, the radar’s range is 22nm..
5. If the SOJ is flying at a range of 50nm.
from the radar, the radar’s range is 6nm..
For 3D implementation of SOJ, the implementation is
the same as in 2D. The effective range of the
victim radar is first determined from the relation
ship above, and the effectiv
e radar range is then used
to determine the radar signal strength, through the
normal radar detection r
outine (see the details of
this in the earlier sub-section titled “
Understanding How Radars Work In Falcon 4.0
.”
As you can see, the high output po
wer of the SOJ totally saturates
the receiver system on the victim
radar, and practically shuts down the radar the clos
er it is to the victim. The jamming power drowns
out all other radar contacts and de-sensitizes the vict
im radar. Unless the radar contact is inside the
effective range, the contact cannot be detected. Es una lectura interesante, explica mucho de como funciona Falcon internamente, aunque hay que cogerlo con pinzas porque es muy antiguo:

Perfect.

La solución que describe alterando el rango de la partida es interesante. Pero no se si se puede alterar el parametro " alcance de deteccion" durante la partida en curso.

Hay dos factores muy importantes en realidad. (ya que me habeis pasado la info de BMS sigo en el otro post abierto para tratar el tema en DCS)
