It wouldn't help even if they had. The Scimitar possessed an advanced cloaking device. Geordi stated that none of the usual anti-cloaking countermeasures (e.g. residual anti-protons) were any use against it.
The only way they were able to locate the Scimitar was that the Reman Viceroy had made a psychic connection to Troi which she was able to use to sense his location allowing the Enterprise to score enough hits to disable the cloak.
