well, radar can be jammed, but there are home on jam modes. IR you have flares and emergency internal heatsinks. Lidar and Radar can be absorbed by Vantablack. many other things

How costly, in terms of power, would it be to do the sort of multi-spectral jamming this Omni sensor would require? Any guesses?
I'm starting to get on-board the 'sensors should be modelled train'. It makes sense not to bother with the tiny elements as Qswitched says, but the composition of the suite would lead to interesting electronic warfare exploration. The rationale for not physically modelling it would be its arrayed nature giving it built in redundancy.
Maybe just model the active components (ie radar transmitter) that would have large bits.

If you have a large number of craft, you can arrange them as to physically obscure the relatively valuable ones, though the ease and effectiveness of this depends on the ubiquity of the enemy's local satellite observation. ICBMs also have decoy warheads which are literally just mylar balloons; maybe capital-sized barrage balloons IN SPACE! would be viable... until someone sweeps a laser across your fleet and pops half of them. My point is that rather than trying to fudge enemy sensors with some kind of complex system, there may be some very simple solutions that don't necssarily render enemy sensors actually incapacitated so much as simply unhelpful regardless.

I quite like the idea of miniature versions of the capital ship as decoys, but I suspect getting the signature to match would be difficult. Especially in light of the fact that the ships signature changes as it manuvers and switches things on and off.
I was reading about how current seekers can also discriminate acceleration profiles that don't match the target. Would that be something you can put in if there is every chance you know nothing about a targets capability?

Given that the accelerations of spaceraft change quite dramatically over the course of their mass expenditure, this kind of target profiling may be of limited use. If you have already identified the enemy craft, however, it's a good way to know how much delta-v they're likely to have remaining since rocket engines don't throttle well.

Presumably missiles would only expose their own cameras for terminal homing. A swarm of missiles could include a number of cold, non-maneuvering sensor drones on nearby trajectories. If you only need 10 seconds of local sensor function, you can do really silly things like using film cameras, which continuously replace the sensing element and so are only disabled by lasers so long as the laser is actively pointed at the camera. The optics would still be vulnerable, but could be similarly protected by an ablative transparent tape continuously-spooling lenscap.

Wait are we ignoring simple command to ship methods for missile homing? seems to me that during combat engagements you can just SACLOS your missile to the enemy.......would be a simple case of corner reflectors at the end of missile and swarming algorithms and a good missile AI/pilot sitting behind armor doing the hard targeting stuff.
or perhaps you can let your IR simply ignore launching flares by giving them a initial lock before launch?

Here is how you protect your optical/IR sensors from laser light without sacrificing sensitivity (much):
