摘要
弹射式干扰功率是对星载SAR实施干扰的前提。从信号角度推导弹射式干扰的干扰方程,分析弹射式干扰功率的影响因素,详细讨论了干扰机等效辐射功率与SAR高度、干扰机高度和干扰信号入射角之间的关系。仿真验证了理论分析的正确性。
The power is the premise of rebound jamming to spaceborne SAR. First, rebound jamming equation is derived from signal processing point of view, and then the factors which impact on the jamming power are analyzed. Finally the relations among the ERP of jammer, the height of SAR and jammer and the incident angle are discussed. Simulation results verify the correctness of the theory analyses.
