Two Methods of Modified Adaptive Channel Equalization

摘要

摘要: 在常規(guī)雷達加裝的自適應旁瓣相消(ASLC)系統(tǒng)中，天線至接收機前端饋線部分的相位不一致性通常不可忽略。而現(xiàn)有的自適應通道均衡方法是在接收機前端注入校準信號進行均衡，只能對接收機的幅相不一致性進行校正，對饋線部分的相位失配卻無能為力，因此影響了ASLC的對消性能。該文提出了兩種修正的自適應通道均衡方法，它們能同時校正接收機與饋線部分的幅相不一致性。理論分析和實驗結果驗證了這兩種方法的有效性。

Abstract: In the Adaptive Side Lobe Cancellation(ASLC) system of general radar, the mismatched phase of transmission line between the antenna and the former of the receiver can not be ignored usually. Otherwise, the existing method of adaptive channel equalization can only equalize the mismatched amplitude and phase of the receiver while it is disabled of the mismatched phase of the transmission line, because the reference signal is inputted in front of the receiver. Therefore the performance of ASLC is affected. Two methods of modified adaptive channel equalization are provided in this article. The mismatched amplitude and phase of the receiver and the transmission line can be revised at the same time by these two methods. The effect of them is proved with the theory analysis and experimental results.
