摘要: 自適應(yīng)陣列中,由于通道的頻帶特性不一致(通道失配),會(huì)導(dǎo)致自適應(yīng)抗干擾性能的嚴(yán)重下降,一種解決的方法是在通道后加抽頭延遲線進(jìn)行自適應(yīng)補(bǔ)償,但是這種方法在通道失配波紋數(shù)較多的情況下,由于需要很多的抽頭延遲線進(jìn)行補(bǔ)償而使得實(shí)時(shí)實(shí)現(xiàn)幾乎不可能,該文提出了一種基于帶寬分割的自適應(yīng)通道補(bǔ)償方法,能在通道失配波紋數(shù)較多的情況下,實(shí)時(shí)并較好地完成自適應(yīng)通道補(bǔ)償,理論分析和計(jì)算機(jī)仿真都證明了該方法的有效性。

Abstract: In adaptive array, channel mismatch may severely degrade an arrays performance, one solution is adaptive compensation with taps added to channel, however, implementation in real time of this method is impossible if there are too many mismatched channel ripples because a good many taps are needed. An adaptive channel compensation method based on bandwidth partitioning is proposed in this paper which can resolve effectively the above problem. Theoretical analysis and computer simulation results demonstrate the effectiveness of the proposed method. -
