Can modern smoke and decoys defeat missile sensors?

Could a modern smoke screen blind targeting sensors as a soft-kill defence?

Combined decoys address several sensors, but improving image recognition could require additional ways to obscure or disable a seeker.

Modern decoy systems combine smoke with chaff and usually flares to create several kinds of interference. An Iowa-class museum display is recalled as describing material that produced both radar and thermal effects, although the precise details are uncertain. Better image recognition could make it necessary to obscure the visible target as well as disrupt radar. The resulting prediction is that more effort will go into disabling missile sensors even when the missile itself is not destroyed.
