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。The output of the detector is the video-signal proper, with a 2-volt swing.
檢波器的輸出是相應的視頻信號、擺幅為2伏。The signal is fed into a filter-amplifier which is transformer-coupled to the video-detector.
