Research on Effect of Helicopter Magnetic Anomaly Detecting Submarine from Change of Submarine Heading
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 value at north heading and south heading,and the minimum value at east heading and west heading.
