| 摘 要： | 从机载雷达功能仿真的目标探测模型出发,以信噪比的求解为基准,考虑机载雷达目标探测过程中受到的大气衰减和地表镜面反射等背景因素的影响和制约,分析了典型大气状况和地表类型条件下目标回波功率的模型.大气衰减系数和地表镜面反射系数经过优化建模,以达到定量计算的要求.利用此模型提出机载雷达目标探测的效能指标.在效能仿真的基础上,运用典型值采样的方法,重点分析了镜面反射对机载雷达回波能量的定量影响.仿真结果表明了该模型的正确性和有效性.

| Abstract: | The target detection simulation mode of the airborne radar is based on the clutters of air attenuation and mirror reflection coefficient, and is analyzed in some typical air and land conditions of environment. Based on the simulation and using the method of sample by typical value, the effect of airborne radar on echo-signal power was analyzed quantitatively. Optimizing the simulation mode of single trip air attenuation coefficient and mirror reflection coefficient which can be calculated quantitatively. A ... |
