摘要: 本文研究了設計參數(shù)具有容差的陣列天線方向圖綜合法;給出了陣列天線容差優(yōu)化的數(shù)學模型;提出了求解容差優(yōu)化問題的數(shù)學方法;建立了直線陣列天線容差區(qū)內誤差任意分布的物理模型;并對激勵幅度具有容差的側射天線陣進行了計算。本文的方法可以最大限度地避免設計參數(shù)容差對天線性能的影響。Abstract: Tolerance synthesis techniques of array radiation pattern are investigated. The mathematical models for array radiation pattern optimization are given, and the methods for solving the problem of tolerance optimization are initiated. The physical model for arbitrary tolerance distribution of array elements is presented. Numerical examples are given for the broadside array in which the excitation amplitude coefficients have tolerances. The methods given in this paper immunize optimally the resulting arrays against the deviations of the design parameters from their nominal values.
