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。
In terms of helicopter hanging pod magnetic survey platform,the background magnetic interference mechanism is analyzed.The helicopter carrier magnetism and the method of pod track calculation are discussed.The magnetic dipole arrays model of the magnetic interference is established.The model parameters are estimated according to the measured data of relevant aircraft.In the wake of example calculation and analysis,the result shows that for the aviation anti-submarine helicopter platform in the detection of magnetic anomaly,the rope will be within the length of 50 m,for the sake of the detection efficiency and the safety of flight.To ensure high accuracy detection of magnetic anomalies,it is necessary to take into account the magnetic anomaly detection interference caused by the platform background magnetic field.
