摘　　要：外辐射源雷达的研究和应用呈现出由地面固定平台向空中移动平台发展的趋势。首先通过信号建模,从理论上分析了机载外辐射源条件下直达波信号对地物杂波空时二维分布特性的影响;然后通过机载外辐射源实验,验证了杂波空时二维分布特性与理论推导结果相吻合。The research and application of passive radar are heading from ground fixing platforms to air moving platforms. The new characteristics of two-dimension space-time distribution in ground clutter will be analysized using the mathematical model. The airborne passive clutter model is consistent with the real-data by the airborne passive experiments.
