【摘要】：针对直升机悬挂吊舱的磁性探潜平台,分析了直升机平台背景磁干扰产生机理,研究了直升机载体磁性和磁测吊舱轨迹计算方法,建立了直升机背景磁干扰磁偶极子阵列模型,借鉴固定翼飞机相关实测数据估算了模型参数。实例计算和分析表明:利用直升机平台进行航空磁性反潜时,考虑到探测效率和飞行安全,吊绳长度不可能达到50m,为确保磁异常的高精度探测,必须考虑平台背景磁干扰对磁异常探测结果的影响。
[Abstract]:Aiming at the magnetic submersible exploration platform of helicopter suspension pods, the generation mechanism of background magnetic interference of helicopter platform is analyzed, and the calculation method of carrier magnetism and magnetic measuring pod trajectory is studied, and the magnetic dipole array model of helicopter background magnetic interference is established. The model parameters are estimated by using the measured data of the fixed-wing aircraft. The calculation and analysis of an example show that, in order to ensure the high accuracy of magnetic anomaly detection, the length of suspension rope can not reach 50 m when the helicopter platform is used for aeromagnetic anti-submarine, considering the detection efficiency and flight safety. The influence of the background magnetic disturbance on the magnetic anomaly detection results must be considered.
