Broadband source location method is investigated by using signal - phase - matching principle, and simulations and experiments are carried out to show the validity of the method ; two high resolution algorithms of broadband signals are proposed, which are the dft interpolation algorithm and the frequency invariant beam space algorithm. the proposed algorithms have no requirement for prior information of source locations, so the results of doa estimation can be unbiased ; a method of temporal - spatial averaging, which can improve the performance of doa estimation for uniform linear arrays, is given. this method can be applied in the most narrowband or broadband eigen - structure based high resolution algorithms
提出了利用信號相位匹配法的寬帶信號方位估計方法並從模擬和實驗兩方面對其進行了驗證；提出了基於dft插值的和基於頻率不變響應波束域的兩種寬帶信號高分辨方位估計演算法，這兩種方法在進行方位估計時均不需要進行方位預估，從而避免了因角度預估可能帶來的估計偏差；最後提出了一種提高均勻線列陣方位估計性能的時空平均法，該方法可適用於多數窄帶或寬帶的特徵結構類高分辨方位估計演算法中。 -
By the theory of z transformation of linear system and matrix, we proved the validation of the averaging filter method using in ietd to cancel oscillation. then we illustrate the disadvantage of using averaging filter and give a new averaging filter that we note as phase - modified averaging filter, which can reduce the disadvantage. at the end of this chapter, we study the potent of reducing the time - cost of ietd by taking account the short duration characteristics of incident impulse
