分数时延估计文档对于宽带信号, 基于移相的窄带波束形成方法会导致方向图波束指向的偏移和主波束畸变, 并且无法有效地抑制宽带干扰。该文提出了基于数字时延加抽头延迟线
(tapped delay line , TDL)结构的宽带自适应波束形成方法。
该方法采用数字时延滤波单元补偿宽带信号在波束指向上的相位和包络偏移, 并用基于TDL 的空时二维滤波处理抑制宽带干扰。分析和实验结果表明, 该方法可以有效地合成空间宽带波束并抑制宽带干扰, 提高信干噪比(sig nal-to-interference-plus-noise r atio , SINR)增益。

一种未知信源数的高分辨DOA 估计算法：众多性能优良的超分辨波达方向(DOA)估计算法通常需要预先判定信源数目，然而，现有的信源数估计
算法在有限采样快拍条件下，估计性能随着信噪比的降低而下降，错误概率也相应增加，最终导致DOA 估计失败。
该文提出一种超分辨的DOA 估计算法，此算法不需要预判信源个数和进行特征值分解，同时在时变环境中，针对
快拍数较少的情况下，依然保持较高的角度分辨能力，可以被认为是综合了Capon 法和MUSIC 法的优点。
Algorithm on High Resolution DOA Estimation
without Sources Number：Many of the super resolution DOA(Direction-Of-Arrival) estimation algorithms presume the number of
signal sources. Since the sample snapshot is limited, however, the available algorithms on source number estimation
may fail at lower SNR. In this paper, a novel algorithm for high resolution DOA estimation is proposed, which not
only skips sources number estimation and EVD, but also behaves satisfactorily with a few snapshot, it may be
viewed as a combination of merit of conventional Capon and MUSIC method. (2013-12-30, PDF, 632KB, 下载34次)
