Title:
ACOUSTIC GUIDANCE SYSTEM
Document Type and Number:
Japanese Patent JP2022171052
Kind Code:
A
Abstract:
To provide an acoustic guidance system aiming for higher observation accuracy of a target and improvement of meeting probability.SOLUTION: According to an embodiment, an acoustic guidance system comprises a guidance propulsion device, an active sonar device and a guidance control device. The guidance propulsion device is loaded in an underwater navigation body and guides the underwater navigation body toward an underwater target. The active sonar device obtains position information of the target using a sonar signal. The guidance control device executes arrival estimation computation on the basis of the position information. The guidance control device comprises a guidance computation part. The guidance computation part supplies the result of the arrival estimation computation to the guidance propulsion device before sending out of the underwater navigation body. The active sonar device comprises an acoustic guidance part. The acoustic guidance part supplies a guidance instruction to the guidance propulsion device by an acoustic communication signal different from the sonar signal after sending out of the underwater navigation body.SELECTED DRAWING: Figure 1
