In this thesis , we mainly discuss the signal detecting of radar echo and the techniques to process them . we labored on pulse integration , correlation detectingand wavelet techniques and their applications in radar area . three types pulse integration are introduced i . e video integration , binary integration and frequency domain intrgration 論文主要詳細(xì)論訴了信號(hào)積累技術(shù),相關(guān)檢測(cè)技術(shù)以及以小波變換這三種技術(shù)在雷達(dá)信號(hào)檢測(cè)和處理中的應(yīng)用,在信號(hào)積累技術(shù)中,詳細(xì)討論了視頻累積,二進(jìn)制累積技術(shù)的基本原理和實(shí)際應(yīng)用。
