| 摘 要： | 根据前人对海浪感应磁场研究的成果,在海浪是平稳正态随机过程的假设下,求出了飞行器接收的海浪感应磁场噪声功率谱的表达式.在讨论功率谱和飞行角度的关系时,发现海浪感应磁场随飞行角度变化,为低频、窄带大干扰或高频、宽带小干扰,并且在某些飞行角度会出现奇点.进行了仿真计算,结果符合理论表达式.

| Abstract: | Based on the previous work on the ocean|wave induced magnetic noise and the assumption of a stationary and normal process, the paper finds the formula of the PSD of the magnetic field by an aircraft moving at constant velocity in the horizontal plane. In the discussion on the relationship between the PSD and the angle between aircraft movement and ocean wave propagation, the paper finds the "power compression" phenomenon and its reason. The simulation result agrees well with the analysis. |
