Sonar detection distance measurement value metering and calibration system and method under pool condition

Abstract

The invention relates to the underwater sound metering and calibration field and especially relates to a sonar detection distance measurement value metering and calibration system and method under a pool condition. The metering and calibration system consists of a pool, a target simulation sonar, a hoisting rack, a standard hydrophone, a measurement amplifier, a filter, a collector, a data controller, and a metering calibration measurement and control platform. The standard hydrophone, the measurement amplifier, the filter, the collector, and the metering calibration measurement and control platform are successively connected to form a metering calibration subsystem used for calibration of a target simulation sonar radiation sound pressure level; The metering calibration measurement and control platform sends a control command to the target simulation sonar via the data controller to make the target simulation sonar emit a target simulation sound signal with specified intensity, and the data controller receives a range finding result output by a sonar to be measured and uploads to the metering calibration measurement and control platform. And finally, the metering calibration measurement and control platform outputs a metering calibration report. In the invention, a metering calibration problem of a sonar large detection distance measurement value under the pool condition is solved.
