海上侦察船的纯方位无源定位技术研究

Research on bearings only passive location technology for reconnaissance ship at sea

海上侦察船的敌方目标定位技术对舰船的海上军事作战能力有关键性的作用,准确地对敌军进行定位和侦察有助于在军事行动中占据有力地位。传统的海上目标探测技术有雷达技术、超声技术等,但存在容易暴露、探测精度低等问题,无源定位是指被动的接收辐射源信号(声音等),确定辐射源的准确位置。本文结合被监测对象船舶的非线性运动模型,设计了一种基于方位角测量技术的纯方位无源定位技术,并解释了系统的工作原理和流程。

The enemy target location technology of the naval reconnaissance ship plays a key role in the naval combat capability of the ship. Accurate reconnaissance of the enemy's azimuth and distance is helpful for the military operation to take the initiative position. The traditional technology of sea target detection includes radar technology and ultrasonic technology, but there are some problems such as easy exposure and low detection accuracy. Passive location refers to the passive receiving of radiation source signals(sound, etc.), and the accurate location of the radiation source is determined. Based on the nonlinear motion model of the ship under surveillance, a bearing only passive location technique based on azimuth measurement technology is designed, and the working principle and structure of the system are explained.
