Method of Solving Motion Factors of Ideal Acoustic Homing Torpedo by Distance and Bearing Observations
摘要
Abstract
To predict the trajectory of acoustic homing torpedo fastly,the distance and bearing relative to this ship for specified time were taken as the torpedo motion factors,and the trajectory was parameterized to the solution of differential equations taking the factors as initial value. The result demonstrates that the analytic solution is equivalent to an algebraic equation, and this transformed algebraic-equation can be calculated using standard Newton method. A detection model of active sonar with the separation of sending and receiving point was established by considering sound speed influence. Based on the observation value of distance and azimuth,a relatively superior criterion named trajectory fitting for solving the motion factor was constructed. The fast calculation was realized for estimating the ideal acoustic homing trajectory under the conditions of small samples. Simulation results show that the torpedo trajectory predicted by this method can meet the parameters calculation for firing anti-torpedo torpedo.关键词
