舰载反潜双机协同定位及其误差估计问题研究

摘要

Shipboard dual-aircraft cooperative locating becomes more and more important in modern antisubmarine war( ASW) .In this paper,a proper method based on Euler equation and differential equation is proposed for computing the position of submarine and estimating the locating error for absolute locating and relative locating problems .It solves the error estimation problem well when two antisubmarine helicopters,the lead and the wing plane,cooperate with each other for locating submarines .The processes for cooperative locating and its error calculation are presented,which is of great significance for ASW .%　　由于现代化反潜战争的需要，舰载双机协同定位变得越来越重要。通过建立欧拉方程和微分方程，巧妙地给出了反潜双机协同定位过程中绝对定位和相对定位的方法，并给出了两种情况下的误差估计表达式，解决了反潜战中通过长机和僚机对潜艇进行协同打击的问题。最后结合实际应用场景给出了协同定位及其误差的计算过程，对于反潜战具有重要的指导意义。
