摘要

摘要: 采用成熟的商用电磁计算软件中的快速多层多极子方法计算了全尺寸飞机目标的全空域全极化双基地散射特性数据，统计了全极化双基地RCS起伏特性，指出4种极化双基地RCS的统计特性类似，而单基地共极化和交叉极化RCS存在较大差异；统计了单/双基地极化比的分布特性，发现单/双基地交叉极化与共极化比情况差异较大，而共极化比类似，所得结论为全极化双基地雷达飞机目标探测试验研究提供参考。

Abstract: Whole space polarimetric bistatic scattering data of full-size aircraft targets were calculated via the mature electromagnetic calculation software.The fluctuation statistics characteristic of the polarimetric bistatic Radar Cross-Section (RCS) was carried out.It was found that the statistical properties of the four polarimetric types (HH, HV, VH, VV) of polarimetric bistatic RCSs are nearly the same, while the monostatic main and cross polarization RCSs statistical properties were quite different from each other.The characteristics of the distribution statistic for the monostatic and bistatic polarization ratio were carried out.Moreover, it was found that the cross-main polarization ratios were quite different, while the main polarization ratios were similar.The statistical results provide a theoretical reference for fully polarimetric bistatic radar aircraft target detection experiments.
