| 中文摘要: |
| 在复杂电磁环境下， 飞行装备很容易受到电磁脉冲的干扰而偏离航线或坠毁， 为了增加其抗干扰能力， 提出了基于ARMA滤波的电磁防护方法。该方法在装备受到电磁干扰无法控制的情况下， 根据先期的轨迹和指令， 通过ARMA滤波器算法， 自动产生控制指令， 用来剔除并更换掉无效的控制指令， 使飞行装备在复杂电磁环境下， 继续沿着航线飞行避免发生坠毁。通过仿真计算及模拟实验， 证明该方法能使飞行装备具有较好的抗干扰能力和 “自修复” 能力。 |
| 英文摘要: |
| Under complex electromagnetic environment, flying equipment is likely to be disturbed by electromagnetic pulses and to prang. In order to improve its immunity ability to electromagnetic pulses, a method of electromagnetic protection was proposed based on ARMA filtering. When flying equipment is disturbed and lost its control, this method can make equipment form control instructions automatically by ARMA filtering based on prior trajectory and instructions. While this restored instructions replace wrong instructions and control equipment flying along lane. Experimental results and simulation demonstrated that this method can improve self-restoring function and immunity ability of flying equipment. |
