引言 引起射束角位置误差的离散配相是限制相控天线阵(φAP)测向精度的主要因素之一。如果不采取特殊措施,那末射束角位置误差可能达到非常大的数值。这样,例如,在φAP孔径上初始相位呈线性分布和阵元相对阵中心的相位不对称时,最大角误差,等于σθ_max≈二(△/2π)θ_0.5p,这里△是配相的 Introduction Discrete phase matching, which causes the error of the beam angle, is one of the main factors that limit the accuracy of the phased array antenna (φAP). If you do not take special measures, then the beam angle position error may reach a very large value. Thus, for example, the maximum angle error equals σθ_max≈ two (Δ / 2π) θ_0.5p where the initial phase over the φAP aperture is linearly distributed and the phase of the array element relative to the array center is asymmetric, where Δ is the phase
