舰载直升机吊声的搜潜方法探讨

针对应召反潜中敌潜艇直线形规避行为,提出了双机协同反潜的预测搜索法. 在一定探测域余量下,使联合探测角度最大,确定了初始探测点.通过预测敌潜艇在舰载直 升机工作时间段内的航程,形成按照两个声纳相背的方向、半径不断扩大的环形搜索路径. 通过Matlab实例仿真,验证此法的探测成功率在70%以上.对实际的舰载直升机反潜具有参 考作用. 

Search method of dipping sonar on ship borne antisubmarine aircraft

To aim at the enemy submarine's linear elusion in the mustering instance of the ship borne antisubmarine aircraft, a forecasting search method b ased on the cooperation of two ship borne antisubmarine aircrafts was proposed.T he initiatory detecting spot was confirmed grounded on the definite detecting su rplus and the maximum combinable detecting angle. Through forecasting the enemy submarine′s voyage at the moment that the ship borne antisubmarine aircrafts wor ked, an arc search path was formed, which ceaselessly enlarged the radius and ap posed the orientation of the dipping sonares. The search method was simulated an d validated by Matlab. The success probability of the method is more than 70%. S o the search method possesses the reference meaning to the actual ship borne ant isubmarine aircrafts.
