摘　　要：针对干扰平台旋转或者在不同方向被探测的情况,该文提出正交多点源反向交叉眼方案,并对方案进行了严格的数学推导和理论分析,得出了角度偏差与其他影响因素的闭合解公式。闭合解公式为与传统两点源反向交叉眼和正交四点源反向交叉眼的对比和评估提供了数学依据,同时为优化方案性能提供了理论依据。通过对比分析了采用正交阵列和线性排布干扰单元的工程实践方法的数学本质。将稳定因数和系统在相同雷达指向角时的角度偏差作为衡量指标,对所提方案和以往的方案进行了数学和实例分析,突显了所提方案在产生稳定的角度偏差方面和产生有效的角度偏差方面的优越性。In the case that the jammer platform rotates or is pointed in all different directions, a new scenario consisting of orthogonal multiple elements is presented, and then rigorous mathematical derivation and theoretic analysis are given for the new scenario. The closed-form solutions for angle error are derived, which is useful in mathematics for comparison and evaluation. Meanwhile, it provides theoretical references for optimizing the performance. Through comparisons, the nature of mathematics for orthogonal arrays and linear arrangement of jamming elements are proposed. Using stability factor and angle error that the systems in the same radar pointing angle as index, mathematics analysis and example are made to prove that the new scenario outperforms the conventional one in the aspect of stability and effectivity.
