目标速度对主动定位误差的影响

Influences of target speed on the error of acoustic localization

超高速鱼雷的出现带来了水中兵器领域的一场技术革命,必将改变海战的作战样式。对超高速鱼雷的探测是与其对抗的前提和基础。由于其航速高达100m/s以上,用现有声呐技术对它进行探测将带来许多新问题。通过研究分析常规声主动定位过程,提出了一种简化模型。运用该模型,分析了在鱼雷跟踪攻击阶段声呐对超高速鱼雷的定位测距误差。仿真结果表明,随着鱼雷速度的提高,常规声呐主动定位精度严重下降,给对抗超高速鱼雷带来极大困难。

Detection of super high speed torpedo is the basis of counterworking. For its high speed （beyond 100 m/s） ,much new problems will occur with nowadays sonar technologies. A simplified model is presented based upon the analysis of normal active localization procedures. Using this model, ranging errors of active sonar to super high speed torpedo at tracking procedure are analyzed. Simulations show that the precision of active localization of normal sonar descends seriously with the increase of torpedo speed, which will bring more difficulties in counterworking to high speed torpedoes.
