| titleOfInvention | An acoustic seawater temperature profiler based on multi-frequency backscatter echo measurement |
| abstract | The invention discloses an acoustic seawater temperature profiler based on multi-frequency backscatter echo measurement. A transducer, and a power supply module, a signal processing module, a signal transceiver module, and an inclination sensor installed in a closed pressure-resistant casing. The present invention extracts the propagation loss difference of multiple transducer receiving signals passing through the path, uses the propagation loss difference to calculate the attenuation coefficient difference, and then uses the attenuation coefficient difference to obtain the corresponding temperature. The invention utilizes the amplitude energy information of the backscattered echo to realize the inversion of the seawater temperature profile. Through the difference calculation of the echo energy, the problem that the target intensity is related to the physical properties of seawater and is difficult to calibrate can be solved. The invention can conveniently and quickly invert the shallow sea temperature profile. |
