웹2016년 9월 2일 · Radar observations play an important role in the emerging, transdisciplinary field of Aeroecology and NOAA’s National Mosaic of 150 NEXRAD radar installations provides a treasure trove of data for population monitoring and studies of phenology, migration, and aerial behavior of “bioscatter” such as birds, insects, and bats. 웹How Radar’s Work. Radars emit a signal, and listen for how long it takes for the signal to bounce back – like listening for an echo. Bats use this same principle when they do “echo-location“. Bats will make a noise, and listen for how long it takes for their noise to echo back. The longer it takes, the farther the object.
웹2024년 4월 7일 · In all such situations, one might use an active remote sensing principle known as echolocation, sonar, or radar. The basic idea is simple. If you can’t see, simply send a signal or pulse of sound and listen carefully to what comes back. Originally developed by nature for bats, it allows them to fly in deep caves without any danger.
