为了对探测系统的空情探测能力做出科学评价,运用排队理论,分析探测器系统对持续空情目标的负荷能力,建立了损失制和有限等待制排队系统下可探测概率的参数模型。通过进一步分析真实战场环境对探测系统可探测概率的影响,给出了探测系统对真实战场环境适应能力量度,并对所建立的可探测概率模型进行修正。通过仿真计算,分析服务强度、服务通道数对系统处理各类强度目标流能力的影响,得到多种情况下的系统可探测概率。

In order to make scientific evaluation of air information detectivity, the capability of sensor system to cope with the air invasion target was analyzed by using queuing theory. A mathematical model of detectivity was established under the losing and limited waiting queuing system. The influence of real battlefield environment on sensor system’s detectivity was further studied, and the measurement of the adaptability of the sensor system to the real battlefield was given. Then, the detectivity model was established more reasonably. Through the simulation and computing, the influence of serving weigh and serving channels on the capability of system to deal with all kinds of weigh targets was analyzed, and the detectivity of sensor system is obtained.
