How to disappear from radar without shutting down?

[Rogue Jedi]

Under normal circumstances to disappear from radar you need to get out of line of sight of all enemy Mechs for a few seconds, if you have a radar deprivation module they loose the lock instantly, or get out of detection range of all enemy Mechs (usualy 800m, 1km if they have Begle or clan Active Probe or the Advanced Sensor Range module, 1,200m if mounting both AP and ASR).

if the enemy have a UAV up within 300m (not precisely sure of detection range but it ls less than 300m) shoot it down, it can detect you regardless of what you are hiding behind or ECM cover

if you are NARCed getting under a friendly Mechs ECM cover is the only way to become undetectable until the NARC deactivates (I think 30 seconds).

"Get out of sight" is the simplest answer.

Unless your enemy is equipped with a 360 Degree Targeting module (which is unusual) you have to be in their forward view and in direct line of sight to be targeted. As long as someone can see you, they can lock you, though, which allows everyone to see you, so make sure someone hasn't flanked around behind you and is relaying information. UAVs, when launched from their consumable modules, also provide a lock on enemies they can see. Locks linger for a time after they lose line of sight on you, with the time being shorter if you have the Radar Deprivation module equipped and longer if they have the Target Decay module or a Beagle Active Probe mounted. Additionally, a Narc beacon will broadcast your location regardless of line-of-sight.

Being within a friendly ECM field (including one that you are mounting yourself) prevents you showing up on the enemy's radar as long as: 1) you are more than 200m away from that enemy's 'Mech; 2) you are more than 360m away from all enemies with a Beagle Active Probe; 3) you are more than 180m away from all enemies with an ECM suite set to counter.

Shutting down is usually the worst option. Sure, they can't see you on radar any more, but you can't move either. Any LRMs that were fired at you are still homing in on your last known location, which is exactly where you are, and every weapon except for the Streak SRM 2 doesn't need a lock to be fired anyway, so if they can see you, they can still hit you, and you're still not moving.

Good advice above, but it should be mentioned that active probes will detect shutdown Mechs as well.

Methods of getting off the enemy's scanners to include seismic:

• Have an ECM
  
• Stand next to someone with an ECM
  
• Stand outside of 850 meters (unless their sensors are enhanced, in which case up to 1,050 meters)
  
• Shutting down (of course; note that within 180 meters a BAP-using mech can detect you)
  
• Stay out of sight
  
• Stand behind another mech or obstacle
  
• Stand on top of the enemy (that you want to get off the sensors of)
  
• Stand behind the enemy
  
• Shoot the spotting enemy in the cockpit
  
• Move slower than 20 kph (lights/mediums up to 40 tons; seismic)
  
• Move only while off the ground (seismic) and land softly
  
• Stand on top of another enemy (leaves you undetected on seismic because you're not moving; he is)
  
• Don't flash tag (has nothing to do with sensors, but my god EVERYONE CAN SEE THE BEAM on thermal / night vision from over 1,000 meters away even if they cannot see you!!!)

(Edit: 850, not 750)

Sensor Range is 800m, not 850 or 750. Advanced Sensor Range Mod OR BAP will take it up to 1000m, and using both takes it up to 1200. Targeting Computers (and, I think Command Console too) increase it as well).

I might add that standing exactly at sensor range still lets them detect you. So standing at 800 isn't any good. Beyond, sure.
But the time it takes to go from 800 to 850 for most mechs below 100 kph is also the same amount of time it takes for the "target decay" to wear off, allowing you to actually leave the target reticule.
A second or less is all that is needed to suddenly appear on someone's radar within 825 meters or less, hence the statement of 850 meters.

Now 1,050 meters is that same margin of comfort range.
Though the percentages I see are still somewhat insane...
1200 meters for both combined.
The safe range is 1,250 just in case.
Now when you add Command Console to that mix...
Tack in the Command Console too, and 1,248 (again, warranting the '+50 meters' for that alone).

So even that 50 meter buffer I gave you... isn't really safe.

Three words:

Radar Deprivation Module

Step behind a rock and voila! You are off the grid!

Chris Roberts had three perfect words for the Radar Deprivation Module:
"This is <redacted>."
On a side note, it is about the only way to have a hint of a chance against LRMs if you can't get close.

If you can get close however, laugh in the face of LRMs and rip that guy's launchers off to beat him with them!

Doesn't even need to be a rock. Cross behind a cable in the TT caldera and it'll break lock. Radar Derp is so broken good it should be on every mech, sadly.

That's true!

Cables are OP. Nerf cables! lol

ECM and staying away from:

- TAG
- NARC
- Enemy mechs (about 1000m or farther away)
