摘　　要：从机载雷达目标探测过程出发,构建目标回波的单程增益系数和地表漫反射的后向散射系数的数学模型,根据此模型提出机载雷达的相应性能指标。在仿真实验的基础上,分析了地球曲率对目标回波和面杂波功率的影响。仿真结果表明了该模型的正确性和有效性。The target detection model of the airborne radar which refers to the single pass gain coefficient and backscattering coefficient was established. A corresponding guide line of airborne radar was given. Based on the simulation, the earth curvature＇s influence to target echo and surface clutter power was analyzed quantitatively. The simulation results show that the structure and mathematical expression are effective and reliable.
