There's nothing for it but to do a full sensor sweep.

"We have been subjected to a full sensor sweep, Captain."

"Run a full sensor sweep of the area around the central power source," Janeway said.

Just do a more active sensor sweep first and report back.

But a sensor sweep of this type, across the entire station, should take several hours, at least.

A very lengthy, prolonged sensor sweep should do the job.

In any case, the first task I set myself was to conduct a long-range sensor sweep.

The sensor sweep began, but there was nothing, not even debris.

Run a sensor sweep on the outside of the station.

Perhaps I should have done more than a routine sensor sweep.
