旁瓣回波
英文
side echo-
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。Side - lobe echo
旁波瓣回波We studied the characteristic of the signals and processing methods. spatially variant apodization algorithm is introduced to significantly reduce sidelobe levels without degrading mainlobe resolution
用sva的方法對回波信號加權，在有效抑制isar回波脈沖包絡旁瓣電平的同時提高信號的主瓣解析度。To the first one, the method of new sidelobe - suppression filter and the method of cutting big signals from the echo are put up, and the result is fine. to the second one, get the echo without earth clutters, and send it to the adaptive system as the input signal, so that the best result can be reached. finally the influence of the bad signal is given
針對旁瓣問題，提出新型旁瓣抑制濾波器方案和從回波中去除大功率信號方案，取得較好處理效果；在和相控陣處理的融合問題上，提出去除回波中地雜波的方法，為自適應處理提供較好的數據源；最後簡要分析惡劣環境對信號處理的影響。分享友人
