1. A monitoring system for improving safety of passengers by sensing an ingress of water into a vehicle, comprising:
a processor; and
a memory storing instructions that, when executed by the processor, cause the processor to:
acquire, from a radar of the vehicle, radar data about a passenger cabin of the vehicle;
determine a current state of the passenger cabin according to the radar data, including determining a height of water in the passenger cabin when present according to the radar data by identifying a presence of the water according to a signature embodied in the radar data and an extent of coverage of the water within the passenger cabin, the signature indicating a difference in density of a volume of the passenger cabin; and
responsive to identifying that the current state indicates an ingress of the water into the passenger cabin, generate a response to the ingress of the water.
