Naval Research Laboratory (NRL) has introduced a remote sensing approach that uses a millimetre wave radar to trace subtle vibration changes from moving targets. The radar will gauge vibrations and reproduce sounds from vehicles through the use of a new algorithm, NRL said Wednesday.
"We showed that if the muffler is vibrating, we can tell if a parked car is on or not. If that car is about to go into gear, we can detect a strong impulse vibration from the gear change," added Rodenbeck.
Rodenbeck noted software modifications on automotive radars will potentially allow current and future vehicles to mitigate road accidents.
