摘要
针对空中多目标进行位置与姿态调整时,影响各目标之间的电磁耦合特性的问题,定义了一种基于雷达散射截面(RCS)统计特性的耦合特性表示方法——耦合量,以仿真试验与内场测量相结合的方法,对双机编队的电磁耦合特性变化规律进行研究。获取了一定空间范围内部分编队因素与电磁耦合特性之间的影响关系,验证了耦合量表示方法的有效性。研究结果可以为多目标RCS耦合性能的评估与优化提供研究思路,具有工程应用价值。
A coupling characteristic representation method based on the statistical characteristics of radar scattering cross-section-coupling quantity is defined with the aim of addressing the issue of influencing the electromagnetic coupling characteristics between targets when multiple targets in the air make position and attitude adjustments.The method of combining the simulation test with the infield measurement is used to investigate the changing law of the electromagnetic coupling characteristics of the two-aircraft formation.The influence relationship between some formation factors and electromagnetic coupling characteristics in a certain spatial range is obtained,and the validity of the coupling quantity representation method is verified.The findings have engineering application value and may inspire future study on the assessment and improvement of multi-objective RCS coupling performance.
