Sonar Signalling Devices TRIZ Cases
- DJ Transform Sound Processing for Time-Frequency Resolution
A cochlea-inspired spring model extracts natural frequencies to improve both temporal and frequency resolution beyond STFT tradeoffs.
- Marine Sonar Orientation Device with Rotating Transducer
A sonar orientation device rotates a transducer assembly via mechanical connectors to adjust transmission direction.
- Rotating Sonar Transducer Array for 3D Imaging
A rotatable sonar transducer array uses interferometry to determine angle information, enabling 3D imaging without requiring watercraft movement.
