电子战系统接收机脉冲截获概率计算公式的修正

Formula Correction of EW Receiver’s Pulse Acquisition Probability

脉冲截获概率是电子战系统接收机的主要指标,可以通过计算接收机的脉冲丢失概率间接得到。现有公开发表的文章只论述了用于计算模拟接收机的脉冲丢失概率计算公式,还未出现可用于计算数字接收机的脉冲丢失概率计算公式。将排队论理论应用到宽带数字接收机的脉冲丢失概率计算过程。由于完全基于概率进行计算,其计算结果具备普适性,为设计师进行宽带数字接收机的资源配置选择提供了理论计算工具。

The pulse acquisition probability is one of primary technical indicators of the receiver of the EW system.It can be obtained indirectly by calculating the pulse missing probability of the receiver.Only the calculation formula of the pulse missing probability of the analog receiver is discussed in the existing published articles,there is no formula for calculating the pulse missing probability of the digital receiver.The queuing theory is creatively used to the calculation of the pulse missing probability of the wideband digital receiver.Because it is completely based on prob-ability calculation,the calculation results have strong universality,also as a theoretical calculation tool,provided for designers to choose the resource allocation of the broadband digital receiver.
