From what I've seen on naval ships you'd launch it to the side that is incoming so you'd be behind the wall of Chaff. I think that would be significantly harder to triangulate because you'd mostly just see the noisy stuff up front and your original target would be behind the wall of chaff. Chaff is also designed to reflect signals all over the place so that it's difficult to get accurate results back. This would make triangulating near impossible (if it's working as intended)
