含腔体导弹雷达截面高频计算建模

在建立了简化含腔体导弹外形模型的基础上,运用曲面像素法、数值积分法、等效电磁流法等多种高频RCS分析方法,采用目标部件分解法计算导弹各散射源的RCS,根据目标各部分散射场间的相对相位关系,计算出导弹整体RCS,这种理论建模方法简单,物理概念清晰,计算量不大,其计算精度虽不如数值计算法、矩量法、时域差分法等精确算法,但结果可为工程设计和导弹探测技术研究提供部分理论依据.

Modeling on High Frequency Calculation of the Cavity Missile's RCS

Based on the simplified mode of the cavity missile,according to the analytic process the RCS of each scattering source were calculated by surface pels method,the numerical integration and method of equivalent current.The final RCS of the whole missile was calculated by the relative phase relation of each part scattering field.The modeling and calculation method is simple and the physical concept is concrete.Although the calculation accuracy is not as good as the calculation accuracy of the numerical calcula...
