声探测精度对深弹命中率影响分析

Impact Analysis of the Acoustic Detection Accuracy on Operational Efficiency of Depth Charge

航空反潜中,水下目标探测定位精度对深水炸弹(深弹)命中率有直接影响。基于吊放声呐探测定位和声呐浮标阵定位两类探测方式,分析目标探测定位精度。对吊放声呐,根据测距测向精度分析其定位精度;对声呐浮标阵,采用基于几何精度衰减因子(GDOP)的浮标阵定位精度分析模型,在满足一定位置误差条件下,计算被动定向浮标交叉定位、主动全向浮标交叉定位、被动全向浮标CODAR阵的定位精度,获得相应的定位精度分布曲线。根据深弹攻击约束条件,分析深弹攻击命中率。给出搜攻潜一体化反潜中,深弹作战的基本使用准则。

In aviation anti-submarine action, the acoustic detection accuracy had a direct impact on oper- ational efficiency of depth charge. Based on dipping sonar detection and sonobuoy array location, the tar- get detection accuracy was analyzed. The location error of dipping sonar was analyzed according to the range accuracy and direction finding accuracy . With the analysis model of Geometry Dilution of Position （ GDOP）, the location error of sonobuoy array, including passive directional sonobuoys, active omni-directional sonobuoys and passive omni-directional sonobuoys （CODAR）, was calculated under the condi- tion of certain position error, and the distribution map of GDOP was presented. According to constraint condition of depth charge attack, the hit rate of depth charge was analyzed, and the basic guideline of depth charge attack was recommended in search and attack of aviation antisubmarine.
