| titleOfInvention | Acoustic positioning method based on multilayer equal gradient sound velocity profile model |
| abstract | The invention discloses an acoustic positioning method based on a multilayer equal gradient sound velocity profile model, which comprises the following steps: establishing a mathematical model of a multilayer equal gradient sound velocity profile; determining state information of a plurality of sensor nodes, and acquiring FDOA information or FDOA information and TDOA information received between the sensor nodes; establishing an arrival frequency model or an arrival frequency and arrival time model between a target node and the position information of the plurality of sensor nodes according to the acquired state information of the sensor nodes and the established mathematical model of the multilayer equal gradient sound velocity profile; and (3) estimating and obtaining the position and speed information of the target node to be positioned by using an FDOA or TDOA and FDOA combined estimation method in combination with the information obtained in the step 2) and the model in the step 3). According to the acoustic positioning method provided by the invention, the sound ray is effectively tracked through the multilayer equal gradient sound velocity profile model, and the error caused by the sound ray linear propagation assumption is reduced, so that the position and the speed of the moving target are more reliably and accurately estimated. |
