摘要

摘要: 在干擾平臺(tái)旋轉(zhuǎn)或者被不同方向的雷達(dá)探測(cè)情況下，該文對(duì)傳統(tǒng)反向交叉眼和正交四點(diǎn)源反向交叉眼進(jìn)行了容限分析。在分析過(guò)程中引入了角度參數(shù)的概念，同時(shí)提出角度參數(shù)特定邊界值(AFSBV)作為評(píng)估兩種方案性能的指標(biāo)。進(jìn)一步推導(dǎo)得出角度參數(shù)特定邊界值關(guān)于相位偏移和幅度增益的閉合解，在干擾平臺(tái)旋轉(zhuǎn)角取值不斷變化時(shí)，得出角度參數(shù)特定邊界值的最大值。這一結(jié)論能指導(dǎo)交叉眼干擾工程實(shí)踐中相位和幅度的取值范圍，使系統(tǒng)能滿足所有干擾平臺(tái)旋轉(zhuǎn)或者被不同方向的雷達(dá)探測(cè)情況。

Abstract: In the case that the jammer platform rotates or is pointed in all different directions for radar detcting, the tolerance analysis is made between the conventional retrodirective cross-eye and the orthogonal four jamming elements. In the analysis procedure, angle factor is introduced. A new criterion called Angle Factor Specific Boundary Value (AFSBV) is proposed to evaluate the performance of the two scenarios. The closed-form solutions for the phase shift and amplitude gain are derived in the following sections. In the case of rotating jammer platform, the maximum value of angle factor specific boundary value is obtained. The results for the amplitude and phase can satisfy the case that the jammer platform rotates or is pointed in all directions for radar detecting.
