摘要：
In the proving of magnetic field of magnetic decoy discharged from a submarine in air, the magnetic field at low altitude is measured on account of the difficulty in proving the magnetic field at high altitude. However, the distribution characteristics of magnetic field of magnetic decoy are different in the different areas at the same altitude. In order to find the most suitable area to be measured, the distribution of magnetic field of magnetic decoy at a certain altitude is analyzed based on the change characteristic parameters in terrain feature statistics, such as standard deviation and roughness, and the terrain entropy in underwater terrain matching field, and a method of choosing the measuring area is studied. The choosing process of measuring area is simulated. And the sea trial is made to verify the proposed method. The results show that the relative measuring error of area chosen by this method is smaller than that of other area. ©, 2015, China Ordnance Society. All right reserved.
