Marine VHF radio. Ships are supposed to maintain a listening watch on Channel 16. Modern radios also have DSC capability to automatically alert when another ship signals distress, even if they’re working a different frequency.
And yes, a large ship would also be monitoring AIS and have onboard radar.
