主动声纳目标定位系统误差修正方法
|
摘要
主动声纳探测水下目标,采用回波延迟时间和舷角进行目标定位,但在水下高速目标探测时,声速的延迟不能忽略,传统的定位方法存在一定的系统误差,需要修正。论文对主动声纳目标定位系统误差简化修正方法介绍的同时,提出收发合置和收发分置主动声纳椭圆修正方法的理论证明。该修正方法适用于对水下高速目标的定位误差修正,为滤波解算目标运动要素提供了理论依据。
Active sonar can locate under water target by the echo delay and receive relative bearing. But sound speed in the water cannot be ignored when active sonar is used to detecting the high speed target. The system error of the usual locating method cannot be ignored either. The paper introduces the simple correction method,puts forward ellipse correction method of monostatic and bistatic sonar systems and gives the derivation. The ellipse correction method is suitable for high speed under water target location error correction,and supports furthermore target motion factor calculation.
