水下高速航行体的航向角和距离估计方法

为了提高反鱼雷鱼雷拦截成功率,实现其对水下高速航行体的航向角和距离估计尤显重要。该文立足于此,探讨一种对水下高速航行体的航向角和距离的估计方法。该方法可同时使用主被动声纳,对来袭水下航行体进行探测。主被动检测时采用初始轴向对准,检测装置直航,应用双周期检测法,可在极短时间内对水下航行体的航向角、距离和速度进行精确估计。文中给出了估计过程的运算公式,指出检测装置对目标方位的检测精度要求均方差不大于0.1°。对不同速度、距离时水下航行体的航向角和距离估计进行了仿真试验,结果表明,在航行体航向角小于35°,距离大于700m时,可得到理想的估计值。该方法对探索反鱼雷鱼雷检测装置的设计和对水下航行体参量的检测,探讨其拦截方法,具有一定的参考价值。

Estimation of Course Angle and Distance for High Speed Underwater Vehicles

It is important for anti-torpedo torpedo(ATT) to estimate the course angle and distance of high speed underwater vehicles so as to enhance the probability of successful interception.This paper discusses an estimation method for both active and passive sonar to detect incoming high speed underwater vehicles.The initial axial alignment method,the straight run of detection device and the two cycles method are adopted to precisely and quickly estimate course angle and distance.The presented formulae for describing the estimation process indicate that the mean square deviation of detection accuracy of target bearing from detection device should be no more than 0.1degree.The simulation tests for the course angle and distance estimation under different speeds and distances are performed,and the results show that the ideal values are obtained when the course angle is less than 35 degree and the distance is greater than 700 meters.This estimation method could be a valuable reference for the research on the design of ATT detection device,the detection of underwater vehicle parameters,and development of interception method.
