A sonar calibration facility is designed for helicopter dipped sonar test and evaluation. Special requirements were, minimize space requirement, minimize ambient noise for low signal hydrophone calibration, treat water to increase cavitation threshold for source calibration. The nearfield calibration array technique provides an accurate, efficient calibration facility that can economically meet these special requirements.
