高精度舰艇声纳测量误差标定方法

High Accuracy Error Method of Naval Vessels Sonar

提出一种基于差分GPS定位综合修正的舰艇声纳测向测距误差标定方法,测向真值提高精度,并消除了由应答器时延引起的距离误差;所提出方法可指导对舰艇声纳测向测距误差的精确标定,保持良好的技术状态。

A method based on differential GPS positioning comprehensive correction for monitoring sonar direction-finding distance error calibration is proposed. The accuracy of direction finding is increased by 40＇ and the range error caused by the delay of the responder is eliminated. The proposed method can guide the accurate calibration of the direction finding and ranging error of the monitoring sonar, and maintains a good technical state.
