引信目标的近场散射特性受到天线方向图、目标局部照射、弹目交会状态等因素的影响,计算过程复杂。首先提出了一种基于FEKO的目标近场散射特性实时仿真方法,然后根据引信作用段的特点建立了弹目交会模型,对引信目标的近场动态散射特性进行了实时仿真,仿真结果表明近场散射强度与导弹脱靶量和目标照亮区有直接关系,脱靶量越小,散射强度相对越大,且弹目距离较近时,由于照亮区的不同散射强度将出现较大起伏。
The near-field scattering characteristics of the fuze target are affected by such factors as the antenna pattern, the target local irradiation and the projectile intersection status, and the calculation process is complicated. First of all, a real-time simulation method of near-field scattering characteristics based on FEKO is proposed. Based on the characteristics of the fuse segment, a projectile model is established to simulate the near-field dynamic scattering characteristics of the fuze target. The simulation results show that the near-field The scattering intensity is directly related to the miss distance of the missile and the target illumination area. The smaller the miss distance is, the larger the scattering intensity is and the shorter the distance of the projectile is, the larger fluctuation will occur due to different scattering intensities of the illumination area.
