相控阵体制机载预警雷达作战效能评估
|
摘要
相控阵体制是未来机载预警雷达发展的重要方向,其作战效能评估目前尚缺乏有效的方法和模型。采用经典的可用-可靠-能力模型(即ADC模型)对相控阵体制机载预警雷达的作战效能进行了建模,将预警雷达状态分为正常、降级和故障3种情况并给出了可用性的计算方法,根据概率论推导了可信性矩阵的计算方法,根据预警雷达探测威力、目标测量精度、目标跟踪能力3个指标给出了能力向量的计算方法。最后对建立的模型进行仿真,仿真结果得到:相控阵机载预警雷达作战效能随单个天线阵元的MTBF增加而增加,随执行任务时间的增加而降低。
The phased array system is an important direction for the future development of airborne early warning radar,but its capability evaluation is lacking effective methods and models yet. The ADC model is selected to model the combat effectiveness of the phased array airborne early warning radar.Calculation method of availability is given by dividing the radar working state into normal,degrading and faulting,while calculation method of the confidence matrix is given based on probability theory,and calculation method of capability vector is given according to the three factors of early warning radar detection power,target measurement accuracy and target tracking ability. The built model is also simulated,which shows that airborne early warning radar performance increases with the MTBF of the antenna element,and decreases with the task time.
