- An estimation algorithm for the arrival direction of wideband signal
一种宽带信号方位估计算法 - 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
提出了利用信号相位匹配法的宽带信号方位估计方法并从仿真和实验两方面对其进行了验证；提出了基于dft插值的和基于频率不变响应波束域的两种宽带信号高分辨方位估计算法，这两种方法在进行方位估计时均不需要进行方位预估，从而避免了因角度预估可能带来的估计偏差；最后提出了一种提高均匀线列阵方位估计性能的时空平均法，该方法可适用于多数窄带或宽带的特征结构类高分辨方位估计算法中。 - Researches focus on the identification technology of joint transform correlator after building the volume holographic storage system . it analyzes the relationship between position of related export signals and position of import images . and it gives the condition that related export signals separates from zero - level flare
