潜艇利用“迪卡斯”盲区规避反潜飞机跟踪

Research on Submarine to Elude Tracking by the DICASS Blind Area

"迪卡斯"声纳阵存在探潜盲区,潜艇可利用其进行规避。通过对盲区的分析和计算机可视化,并建模、仿真计算了"迪卡斯"声纳浮标阵对潜跟踪概率,得出了通常情况下、特殊情况下潜艇机动规避方法和规避过程中的速度优化方法。尽管利用盲区规避可造成反潜飞机探测或定位中断,但利用盲区并非任何情况下的最优方法。

DICASS have detection blind areas,the submarine can use it to evade. Through Analysis and computer visualization of the DICASS blind area,and through modeling,simulation calculating the probability of the submarine tracked by sonobuoy arrays,educed the maneuver eluding methods which can be used by submarine to elude tracking by DICASS in usual and special situation,and how to optimize the speed of submarine during tracking elusion.Although it will cause breaking off of AS-aircraft＇s detection or position by using the blind area to evade,using of the blind area is not the best measure on any conditions.
