导出了角锥喇叭增益衰减因子的新表达式。他们提供了快速和准确的喇叭方向性计算，无论是线性的二阶形式。这些方程比精确方程更容易计算，精确方程涉及复杂的菲涅耳积分。公式表示的增益降低因子，在孔径的二次相位误差的基础上。<<ETX>>
New expressions for the gain-reduction factors of a pyramidal horn are developed. They offer fast and accurate computation of the horn directivity, in either linear of second-order form. These equations are much easier to evaluate than the exact equations, which involve complicated Fresnel integrals. The formulas are expressed in terms of gain-reduction factors, based on the quadratic phase errors in the aperture.<<ETX>>
