一种改进的均匀直线自适应天线阵

针对常用的自适应算法都需要复杂的来波方向估计过程，而且方向估计误差会使自适应阵性能恶化的问题，以均匀直线阵为研究对象，提出了一种改进的自适应算法。通过引入阵列导向矢量，使自适应阵具有波束搜索能力，避免了复杂的来波方向估计过程。提出了相应的系统实现方案，通过对16元直线阵的仿真试验，证明了该算法是有效的。

Improved uniform linear adaptive array for interference cancellation

Aiming at the problem that the conventional adaptive algorithm generally needs to estimate the direction of arrival signal beam and that the error of direction estimation will worsen the performance of an adaptive array, an improved adaptive algorithm is proposed here, based on a uniform linear array. By introducing the array steering vector, the ability to search for the desired signal beam is obtained by the adaptive array, so the complicated process for direction estimate is avoided. Its system scheme is also presented here. Finally, the validity of the algorithm is verified by the simulation experiment on the 16-units linear array.
