摘要
脉冲丢失概率是雷达信号截获系统的重要问题。用概率方法分析了具有同时多信号截获能力的系统脉冲丢失概率,能够直观地为总体系统方案设计提供参考。宽开单信号截获系统在脉冲流量较小时截获概率较高,在流量较大时截获概率急剧降低;宽开单信号截获系统和频率引导单信号截获系统的脉冲丢失概率一致。频率引导多信号截获系统的多信号能力对截获概率的影响不是很显著。要实现高密度环境下的高信号截获概率必须采用宽开多信号截获系统。
The research of dropped probability of pulses in electronic intercept system is a signifi- cant topic with the capability of simultaneous multi-signal processing, but it is not addressed in those traditional approaches. The dropped probabilities of pulses for two kinds of multi-signal intercept systems are analyzed by the help of possion stream model. In low pulse density environ- ment case, a wide open receiver with single signal processing capability can also provide high probability of interception. But when pulse density is increasing, its probability of intercept is sharply decreasing. The probability of the wide open receiver with single signal processing capa- bility and that of the frequency-cued wide open receiver are approximately same. The multi-sig- nal processing ability of a frequency-cued receiver has a less effect on the probability of inter- ception. In order to achieve the ability of high probability of interception, the wide open receiver system with multi-signal processing capability is the best option.
