The master dissertation introduces passive correlative orientation system and base theory in signal dispose briefly in the first place. the system takes tv sound fm signal from tv satation signal. the power rate of tv station signal to sound signal is ten to one. in the case of submerged by mussy weave and machine ' s hot noise, dispersed target signal is feeble
系統採用電臺的電視伴音調頻信號，其中電臺信號與伴音信號功率之比基本為10 ： 1 ，並且目標散射信號較弱，一般情況下淹沒在雜波和機器熱噪聲之下，採用常規的脈沖檢測方法很難對遠距離的目標進行檢測，而以電臺直達信號作為參考與目標回波信號進行相關檢測；系統中信號的相關處理會產生旁瓣，而強目標的旁瓣會影響附近的弱目標檢測。 -
