- source number detection 信号源数目估计
- Given the sampled data of each element, the signal processing of AAA consists of three parts: the determination of source number, the DOA (Direction of Arrival) multi-user detection and DBF (Digital Beamforming). 在给定各阵元的取样数据后,自适应阵列天线信号处理的问题一般可以归结到三个方面:信号源数目的确定、波达方向(DOA: Direction of Arrival)的多用户检测和数字波束形成(DBF: Digital Beamforming)。
- These methods can not give very accurate source number decision because of the lack of DOA information. 当信源数目估计过少时,将影响测向效果,而过多时则无法去掉虚假信号。
- A Method of Target Number Detection in Formation 一种编队目标架次检测方法
- The result of Western blotting showed that the dynamic changes of ICOS protein was identical with the changes of positive-cell number detected by immunohistochemistry. Western- blotting检测结果显示 ,ICOS蛋白的动态变化与免疫组织化学显示的阳性细胞数量变化一致。
- Most of the existing source number decision methods do not use the direction of arrival (DOA) estimation results, and can be called a priori decision method. 由于使用的信息较少,这类方法很难给出信源数目的准确估计。
