【摘要】:旁瓣對(duì)消是一種有效的自適應(yīng)干擾抑制方法。文中介紹了一種模數(shù)結(jié)合的旁瓣對(duì)消系統(tǒng)的結(jié)構(gòu)和工作原理,提出了基于迭代的閉環(huán)旁瓣對(duì)消方法。利用該方法,可在模擬端連續(xù)輸出干擾抑制后的信號(hào);當(dāng)信號(hào)發(fā)生變化時(shí),該方法能實(shí)時(shí)更新旁瓣對(duì)消系統(tǒng)的干擾抑制權(quán)值;通過權(quán)值的持續(xù)迭代,還能夠自動(dòng)修正系統(tǒng)中一些非理想因素帶來的影響,使系統(tǒng)的旁瓣對(duì)消權(quán)值靠近最優(yōu)解。通過使用這種閉環(huán)迭代方法,可以使原來的旁瓣對(duì)消系統(tǒng)更實(shí)用。
[Abstract]:This paper introduces the structure and working principle of the side lobe cancellation system based on the modulus combination , and proposes an iterative closed - loop side lobe cancellation method . By using the method , the interference suppression weight value of the side lobe cancellation system can be updated in real time . When the signal changes , the influence of some non - ideal factors in the system can be updated in real time .
