机载预警雷达作用距离对探测效能的影响

摘要

The airborne early warning radar's detection effectiveness tends to be affected by its detection range as well as its detection probability. A method of evaluating detection effectiveness is given based on probability analysis method,and the probability distribution function of detection effectiveness is obtained based on the detection probability density function. Thereby the mapping relationship between detection range, detection probability and detection effectiveness is established. Finally, an analytical calculation is made, with E-2C and E-3B early warning radars as examples, so as to verify the validity of the method.%机载预警雷达探测效能的高低受雷达作用距离和发现概率的影响,在概率分析基础上提出了一种机载预警雷达探测效能评估方法,通过发现概率的概率密度函数求得探测效能的概率分布函数,从而建立了雷达作用距离、发现概率与探测效能之间映射关系,将作用距离的远近量化为探测效能的高低,并以E-2C和E-3B预警机预警雷达为例进行分析计算,验证方法的有效性.
