Q&A 03:

Will radar still have a passive mode, and if so, how does it work? –Octobit
[DAVID] Yes, radar will have an active and a passive mode. Our current plans are for the passive radar to have a reduced detection range and limit a lot of the electronic and information warfare equipment on your ’Mech as well as the electronic communication between you and your lance. The benefit is that you become a lot harder for enemies to detect, leading to greater chances to surprise or spy on them.
Though, from the same Q&A:

Will a satellite overview be a sort of "ping" on the map of all enemy targets that lasts the duration of the satellite or will you be able to hide from it? –Damocles
[DAVID] The satellite scan will be like a radar sweep of the map, revealing information about enemy positions, but this information will quickly decay. We have not yet decided if or how a ’Mech can escape detection (other than taking shelter in a covered area like a cave) but there will likely be methods of doing so. This is more likely to be true if we implement different kinds of satellite sweeps (i.e. thermal, magnetic, etc.).

If I produce a lot of heat like shooting (an) alpha strike, a PPC or something similar, will I be more (easy) to spot on the radar? –Sir Aaron
[DAVID] Running around with excessive heat won’t affect how you show up on normal radar, but you will stand out to enemies using thermal vision mode as well as any thermal sensors in the battlefield.
So, while going turning one's radar off might make you harder to detect, it also hinders one's ow ability to detect threats.
Additionally, there may be other sensors that can pick up other aspects (heat, magnetic fields, etc), and the satellite view may allow one to be seen from a bird's-eye-view, regardless of whether one's radar is in passive or active mode...
