摘　　要：针对潜艇航向对直升机磁异探潜的影响,文中通过仿真进行了分析。首先利用潜艇磁场的磁感应强度模型以及直升机的磁异探测模型建立了潜艇磁场的磁异常模型,然后依据磁异探测能力指标曲线通过仿真对潜艇处于不同航向时磁探仪的磁异探测能力进行了评估。结果表明,未消磁的情况下,磁探仪探测宽度在南北航向分别取得极大值和极小值;良好消磁的情况下,磁探仪探测宽度在南北航向取得极大值,在东西航向取得极小值。Aim to the influence of the submarine heading to the magnetic anomaly detecting- submarine ability of helicopter is analyzed through the simulating experiments in the paper. Firstly, through both the submarine magnetic induction intensity model and the magnetic anomaly detection model of the helicopter, the magnetic anomaly model of the submarine magnetic field is established. And then the magnetic anomaly detection ability of the magnetometer with the change of the submarine heading is evaluated through simulated experiments based on the magnetic anomaly detection ability index curve. The experiment results are showed as follows. In the case of no degaussing, the detection width of the magnetometer attains the maximum value and the minimum value at north heading and south heading respective. In the case of well degaussing, and the detection width of the magnetometer attains the maximum wlue at north heading and south heading, and the minimum value at east heading and west heading.
