摘要
该文利用严格的电磁散射理论,推导了基于振幅和差式和相位和差式单脉冲雷达测角原理的复杂目标角闪烁的一般表达式,对雷达目标角闪烁的两种物理概念提出了新的解释和认识,揭示出波前畸变概念、能流倾斜概念和雷达角噪声产生原理三者之间的内在关系。该文工作为角闪烁的正确理解、建模仿真和抑制提供了理论依据。
Based on ElectroMagnetic (EM) theory and the monopulse radar angle measurement principle, the formulae of angular glint for complex target are proposed and generally applied to tackling practical problems. The inherent relations among the three representations of radar angular glint, i.e. the phase-front distortion concept, the energy-flow tilt concept, and the monopulse radar angular noise concept, are clearly demonstrated. The two existing concepts of angular glint are also revised. Thus, a firm theoretical foundation for understanding, modeling, simulating and suppressing the angular glint from complex radar targets is established.
