卫星下行链路对抗中最佳干扰区域空间模型研究

Space Model of the Optimal Jamming Area for Satellite Down-Link Countermeasure

在卫星下行链路空基对抗中,确定最佳干扰区域对保证干扰能量有效进入被干扰地面接收终端具有重要意义。文章将现有最佳干扰区域空间模型从地球同步轨道扩展到任意运行轨道,以球面坐标系建立了精确的干扰空间模型,重新定义了最佳干扰区域几何,求解了最佳干扰区域相关参数,得到了精确性更高和适用性更强的结果。

The optimal jamming area for air-borne countermeasure to satellite down-link greatly affects the jamming power entering into the jammed receptor.The paper presents an improved model,which establishes a space jamming model based on the sphere coordinate,redefines the geometry of the optimal jamming area,and computes its new geometry parameters.Comparing to the original model,the improved model replaces the space rectangular coordinate with the sphere coordinate,and can be extended to arbitrary satellite orbit,receptor and jammer,so the results are more accurate and more applicable.
