Abstract

Abstract: A sonobuoy system with the functions of difference global positioning system (DGPS) and short-wave communication is presented to acquire the sound speed profile (SSP) in a large area of sea as quickly as possible. The conventional SSP inversion algorithms based on sound transmission time have to trace eigen ray for every SSP, influencing the inversion speed. A perturbation method is proposed to calculate the sound transmission time quickly, and the time is used as cost function to invert SSP in some area of South China Sea. Results indicate that the sonobuoy is stable and reliable under four level sea state. Although the root mean square (RMS) error is doubled in comparison with that by conventional algorithms, the calculating time can be reduced from 10 hours to 3 seconds by perturbation method. Therefore the sonobuoy system and inversion algorithm introduced in this paper can satisfy the demand of real-time SSP monitoring.
