摘要
高强度的电磁脉冲能够干扰、毁伤敏感的电子设备,特别对空中的飞机、导弹构成了严重威胁。计算了辐射强电磁脉冲对空中目标的作战区域,其大小取决于目标所在高度、波束角和倾角。推导出作战区域各典型点处的功率密度计算公式,考虑电磁脉冲在大气传输中的衰减,最后对一定距离上的晶体混频器造成毁伤所需的辐射功率进行了仿真,研究结果可为探讨强电磁脉冲的毁伤效应提供理论依据。
Many types of sensitive electronic equipment, especially for planes and missiles in the air, can be disturbed or damaged by high power electromagnetic pulse. The coverage area for targets in the air affected by the height of targets, wave beam angle and obliquity angle is calculated. The formulas of power density at some typical points in coverage area are deduced, and the transmission attenuation model of electromagnetic energy is established. Lastly, certain simulation for the needed condition to burn the crystal mixer is done. The results can be used as important references to discuss the damage effect of high power electromagnetic pulse.
