反潜巡逻机具有速度快、航程远、续航时间长等特点,是重要的航空反潜兵力.磁探仪具有不受水文气象条件限制、可以连续搜索、使用简单可靠、分类能力好、定位精度高等特点,是现代反潜飞机,尤其是固定翼反潜巡逻机普遍使用的反潜探测设备.本文依据反潜巡逻机磁探仪实际搜潜过程,建立了磁探仪探潜的地磁北坐标系和磁探仪探测相遇坐标系,并基于这两种坐标系,建立了目标磁异常信号模型,仿真分析了反潜巡逻机飞行航向、飞行速度、飞行高度及反潜机与目标横向距离的变化对目标磁异常信号分布的影响.

英文摘要：

Anti-submarine patrol aircraft is an important aviation anti-submarine forces which has char- acteristics such as the speed is quick, the voyage is far, the cruising time is long and so on. The magnet- ic finder is a kind of anti-submarine detection equipment which is universally used by the modern anti- submarine aircraft, especially the fixed wing anti-submarine patrol aircraft. It has the characteristics such as not being restricted by the hydrological conditions, can continuously search , use is simply relia- ble, the classification ability is good, the positioning accuracy is high and so on. According to the actual process of searching for the submarine which is used by the magnetic anomaly detector of the anti-sub- marine patrol aircraft, this paper established the geomagnetic north coordinate system and the magnetic finder detection meet coordinate system which is used by the magnetic finder, and based on these two kinds of coordinate systems, the target magnetic anomaly signal model is established. Finally, simula- tions about the flight course, flight speed, flight altitude of the anti-submarine patrol aircraft and the in- fluence of lateral distance change between the anti-submarine plane and the target to the target magnetic anomaly signal distribution are conducted.
