Episode notes
SONAR's Nature-Inspired Roots
- SONAR uses sound waves underwater to navigate and detect objects, a principle inspired by nature.
- Its initial development during WWI included the first active sonar system that detected submarines at nearly 1,500 meters.
Bats Inspired Echolocation Discovery
- In 1938, Donald Griffin and Robert Gallimbos demonstrated bats use ultrasonic pulses and echoes for navigation.
- This discovery coined the term echolocation and showed bats use a natural form of sonar.
WWII Accelerated Sonar Innovation
- WWII accelerated sonar technology for submarine detection, with both Allied and Axis innovations.
- Systems like the British ASDIC and German GHG shaped underwater warfare's tactical landscape.
