  4. Civil air defense alarm system was a system to dispense antiaircraft alarm sig - nal, hand hostile air attack informational communication to urbanite at wartime. it is a particular informational communication system of the civil air defense depart - ment, and can not be taken place. at the development trend of digitaliza - tion, unitization, integration of civil air defense communication, the civil air defense alarm system is developing too, for adaptation to the require of both future war and peaceful dual, and enhancing civil air defense communication system ' s directing automation. in recent years, development of different kinds of communication technology infuses new clearly energy into communication, especially spread spectrum communication, because of its strongly interference - free feature, invisibility best, realizable code division multiple access and antimultipath wane and so on merit, gets extensive use at wireless region ; the corresponding spread spectrum chips emerge as the times and get boom, which provides advantag e to realization of the circuit of spread spectrum communication. at the same time, in company with the advance of electronics level, the single chip microcomputer has a great development, world renowned chip manufacturer pushout respective products one after another, the kinds of which are too many to statiste

    在人防通信的數字化、一體化、綜合化必然的發展趨勢下，人防警報系統也不斷發展，以適應未來戰爭和和平時期的雙重需要，提高人防通信系統指揮自動化。近年來，各種通信技術的發展給通信注入了活力，擴頻通信更因其抗干擾能力強、隱蔽性好、可實現碼分多址和抗多徑衰落等優點在無線領域得到了廣泛應用；其相應擴頻處理晶元應運而生並得到迅速發展，這為擴頻通信的電路實現提供便利。同時隨著微電子工藝水平的提高，單片微型計算機有了飛躍發展，世界上著名的集成電路晶元製造商紛紛推出各自的產品，單片機型號之多，已達到難以統計的地步。
