摘要
在深入分析了影响飞机生存力的几种因素的基础上,通过理论推导,建立了雷达输入端信噪比与发现概率及雷达散射截面面积与信噪比之间的关系,计算了雷达散射截面面积对发现概率影响。并在M atlab的环境下进行了数学仿真,仿真结果表明:当信噪比落在区间[5.6,12.5]内,发现概率随着信噪比的降低而陡降。在没有完全掌握敌方预警雷达参数的情况下,通过假设定量的给出调整雷达散射截面面积的最佳范围。
On the basic of deeply analyzing of several factors that affect the survivability of aircrafts, the paper establishes the relationship between detection probability and Signal - to - Noise, and the relationship between Radar cross section area and Signal - to - Noise, calculates the effects of Radar cross section on the detection probability. After simulation in the Matlab environment, we can see that when Signal -to- Noise falls in region [5.6,12.5 ], the detection probability falls steeply as the Signal - to - Noise falling steeply. Without totally knowing the enemy's radar parameters, we give out the best region of adjusting Radar cross section area through assumption.
