And it also has the characteristics of low probability of intercept and multiple access secure communication 并具有信息隱蔽、多址保密通信等特點(diǎn)。
The low probability of intercept ( lpi ) , the ability in super - resolution and anti - jamming of ultra - wide band radar challenge to the traditional receivers 超寬帶雷達(dá)具有低截獲性及抗偵察、抗干擾、抗摧毀等性能,對(duì)傳統(tǒng)的偵察體制提出了巨大的挑戰(zhàn)。
The advantages of spread spectrum communication are as follows : low probability of intercept , good anti - fading and anti - multipath interference capability . it is widely used in military and civil communication 擴(kuò)頻通信具有低截獲率、抗衰落能力強(qiáng)、抗多徑干擾等優(yōu)點(diǎn),廣泛應(yīng)用于軍事通信和民用通信。
Because of using spread spectrum technique , phase - coded radar has good anti - jamming capability and low probability of intercept property . so more and more attention has been paid to the research on it for military and civil application 相位編碼雷達(dá)采用擴(kuò)頻技術(shù)使其具有良好的抗干擾能力和低截獲概率特性,因此在軍民兩用方面其研究日益受到人們的關(guān)注。
The techniques of low probability of intercept ( lpt ) are developing rapidly , and are used widely in radar and communication . in order to counteract the lpi techniques , there is necessary to research the new methods of detection and estimation of lpi signals 目前低截獲概率( lpi )技術(shù)發(fā)展迅速,并在雷達(dá)和通信中獲得廣泛應(yīng)用,為對(duì)抗這些技術(shù)帶來(lái)的檢測(cè)和估計(jì)問(wèn)題,需要研究低截獲概率信號(hào)檢測(cè)和估計(jì)的新方法。
