摘要

摘要: 針對干擾平臺旋轉(zhuǎn)或者在不同方向被探測的情況，該文提出正交多點源反向交叉眼方案，并對方案進(jìn)行了嚴(yán)格的數(shù)學(xué)推導(dǎo)和理論分析，得出了角度偏差與其他影響因素的閉合解公式。閉合解公式為與傳統(tǒng)兩點源反向交叉眼和正交四點源反向交叉眼的對比和評估提供了數(shù)學(xué)依據(jù)，同時為優(yōu)化方案性能提供了理論依據(jù)。通過對比分析了采用正交陣列和線性排布干擾單元的工程實踐方法的數(shù)學(xué)本質(zhì)。將穩(wěn)定因數(shù)和系統(tǒng)在相同雷達(dá)指向角時的角度偏差作為衡量指標(biāo)，對所提方案和以往的方案進(jìn)行了數(shù)學(xué)和實例分析，突顯了所提方案在產(chǎn)生穩(wěn)定的角度偏差方面和產(chǎn)生有效的角度偏差方面的優(yōu)越性。

Abstract: 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.
