导弹头共形阵的射线寻迹及UTD参数计算

Ray Tracing and UTD Parameter Calculation of the Missile Conformal Array

本文根据微分几何原理，导出了与导弹头并形的旋转抛物面上绕射场的UTD参数的计算公式。通过拟椭球积分得到了旋转抛物面上短程线的解析式，避免了数值方法射线寻迹的复杂性，同时简化了UTD参数的计算。这些公式是UTD法计算并形阵的辐射特性和耦合特性时所必需的。

This paper presents the calculation formulas of UTD parameters on the revolutionparaboloid which conforms with missile according to differential geometry. Explicit expressionsare obtained by pseudoelliptic integral which avoids the complexity of geodesic ray tracing bynumerical approach and simplifies the UTD formulas. These are necessary for the analysis ofradiation and mutual coupling of conformal arrays.
