interception n. 1.拦截;截击;遮断,阻止;截取。 2.窃听,侦听;【航空】雷达侦察。 long-range interception【航空】远距离雷达侦察。 blind interception【航空】(用仪表)盲目拦截。 ground-controlled interception【军事】地面控制截击(设备)。
probability n. 1.或有;或然性。 2.【哲学】盖然性〔在 certainly 和 doubt 或 posibility 之间〕。 3.【数学】几率,概率,或然率。 4.或有的事;可能的结果。 5.〔pl.〕〔美俚〕天气预测。 What are the probabilities 有几分把握? The probabilities are against us [in our favour]. 趋势对我们好像不利[有利]。 hit probability 命中率。 in all probability 很可能,大概,多半,十之八九。 probability of (missile survival) (飞弹不被击落的)概率。 The probability is that ... 大概是…,很可能是…。 There is every probability of [that] ... 多半有,多半会。 There is no probability of [that] ... 很难有,很难会。
In modern communication , direct sequence spread spectrum communications was widely used in the fields of telemetering and telecontrol systems , because of low interception probability , its high noise resistance and good security 在现代通信中,直接序列扩频通信技术以其截获概率低、抗干扰性强、保密性高等优点,在航天测控领域得到了广泛的应用。
A interception probability reduction theory by means of comparing the rppm with constant pri pulse sequence is also analysised in this paper , further more the strong properties of eccm of the rppm is discussed and analysised 此外,本文还介绍了随机脉位调制信号比较于等重复周期( pri )脉冲信号来降低信号被截获概率的原理,讨论并分析了随机脉位调制脉冲多普勒雷达较强的抗干扰能力。
