跳頻擴展 的英文怎麼說
中文拼音 [tiàobīnkuòzhǎn]
跳頻擴展
英文
fhss:frequency hopping spread spectrum-
Modern military tactics cooperativity communication raises many new requirements including multi - mode, multi - band, and expandable performance, etc. so, developing new fh station has important sense in military strategy
現代戰術協同通信也對軍用電臺提出多模式、多速率、可擴展等許多新的要求。因此，研製新型跳頻電臺具有十分重要的戰略意義。With the development of communication technology, the communication signal environment is getting more and more complex. fh ( frequency hopping ) signal is used widely in the battlefield, and direction finding becomes an important method to get communication information
隨著通信技術的迅速發展，跳頻、直擴等信號在軍事領域獲得廣泛應用，測向成為情報獲取的主要手段之一。Depending on the development of reconnaissance and interference techniques, spread - frequency communication is gradually becoming the effective communication manner in order to reduce the probability of being captured or interfered, to enhance the security of communication, and to improve the anti - jamming ability of the communication system
隨著通信偵察和干擾技術的發展，為了降低通信過程中被截獲、被干擾的概率，提高通信的可靠性，增強通信系統的抗干擾能力，擴頻通信逐漸成為現代通信的一種對抗干擾的有效通信方式，跳頻通信是擴頻通信中的一種。Frequency - hopping ( fh ) is a novel spread spectrum communication technique, which develops very fast in military field due to its lpi / lpd ( low probability of intercept / detection ) properties and immunity against interferences, the extensive application of hf / vhf ( high frequency / very high frequency ) frequency - hopping radios in military has greatly enhanced the ability of military equipments against jamming and interception and ensure the safety and validity of chain of military command
跳頻技術是擴頻技術的一種，是80年代以來出現的一種新的通信方式。跳頻通信具有良好的抗干擾性，低截獲概率及組網能力，因此跳頻技術的一出現，便在軍事領域得到了極大的發展。採用跳頻技術的短波超短波電臺在軍事通信中得到了廣泛應用，極大地提高了軍事裝備的抗截獲和抗干擾能力，保證了軍事指揮系統的安全和有效性。Every few milliseconds, a fhss signal bounces between different specific points in a designated " spread " of the electromagnetic spectrum, reducing interference from other signals and making it very difficult to eavesdrop on the transmission
每隔幾毫秒， fhss信號在指定「擴展」的電磁頻譜的不同頻率點上跳動，減少其它信號的干擾，使它在傳輸中難以被竊聽到。In chapter three, the theory of particular anti - jamming technologies are analyzed, especially the spread spectrum ( ss ) is one of the most important anti - jamming technologies, including direct sequence spread spectrum ( dsss ), frequency hopping spread spectrum ( fhss ) and other improved technologies
第三章研究了時域、頻域、功率域多種抗干擾技術的抗干擾機理和定量描述抗干擾能力的方法，其中擴展頻譜技術是主流的抗干擾技術，包括直接序列擴頻和跳頻技術以及它們的改進方案。Ss - ffh distribution automation using distribution line carrier systems - lower layer profiles - spread spectrum - fast frequency hopping ss - ffh profile
