摘要
针对复杂雷达动目标的建模仿真及动目标雷达散射截面分析的问题,提出了一种外形建模和电磁散射计算的方法。该方法利用openGL对某型飞机进行了较为精确的外形仿真建模,运用图形电磁算法计算了静态雷达散射截面,并利用一种抖动模型计算了动目标雷达散射截面。通过将仿真结果与静态值进行比较,证明了在叠加抖振前后雷达散射截面有较大的变化。得出了结论。
To investigate the modeling of the complicated radar moving object and the effect of the random wobble on dynamic radar cross section, a method of figure modeling and electromagnetic scattering calculation is presented the figure of the plane is modeled accurately, with openGL the static radar cross section is calculated with GRECO and the RCS of the moving object is calculated with a random wobble model. The comparison of the dynamic value and the static value, shows that the effect of the random wobble on dynamic radar cross section is obvious.
