"splash out, repeat over"
I went to the Classic Battletech forums and asked the writers what they meant about some rules from advanced Battletech expansions that I disagreed with other posters here, over rules saying you had to be within the radius of the Guardian ECM to disrupt sensors. I asked:
"For clarifications sake, though, can anybody tell me if the line "to be affected, the spotting unit must be in the normal operating radius of the ECM... LOS does not affect this radius," means ECM interference with sensor spotting rules on page 224 requires the spotting unit has to be within the 180 meter ECM bubble projected by the Guardian to be affected by ECM, or does any line of sight crossing in to it get countered by the ECM, like how ECM defeats attacks augmented by Artemis that cross through the bubble?"
They said:
"In order for ECM to have an effect in Doubleblind rules, the affected unit must be within the ECM's bubble. It is not sufficient for an ECM bubble to be in line of sight.
Note that the updated Ghost Target rules can provide for a de-facto screening operation with ECM suites.

So pretty much, the rules governing ECM say that outside of 180 meters a target is able to be targeted and tracked, but the scanning rules say that the target's identity is concealed, which could be implemented in MWO as disguising the chassis type, damage and loadout information from a targeting 'Mech. When you close into the 180 meter bubble, there is a high chance that your standard sensors will be confused and unable to lock, in which case you should be able to use other scanners (which have been announced to be released in the future as modules) to track an ECM protected enemy.
A third mode, Ghost Target mode (which the Battletech developers linked their most recent rules to), should be implemented to provide a screen against LRM's/Streaks and what not, but shouldn't provide a hard counter against them (ie lock invulnerability) for the sake of game balance. It could be implemented in several ways, the easiest to provide the lock time increase that ECM currently gives without having to be in Ghost Target mode.
A more complex way (and more interactive) to implement Ghost Targets would be for fake targets to appear on the enemy's minimaps, that are targetable that the enemy would have to cycle through to find a valid target. Like the source material describes, Beagle could help see through the ghost targets, making Beagle useful against that mode of ECM.
