摘要

我们提出了一种多信号自适应空间滤波方法，该方法推广了对已知到达方向的单个信号进行自适应空间滤波的经典方法。此外，还给出了改进的Capon测向方法的计算公式。极限跃迁和无线电监测和无源雷达系统中典型信号接收条件的数值模拟结果证实了基于最大似然法获得的关系的可靠性。

Adaptive Processing of a Set of Signals in Antenna Arrays with Extended Reception Band

We propose a method of multisignal adaptive spatial filtering, which generalizes the classical method of adaptive spatial filtering of a single signal with a known arrival direction. Additionally, the formulas for the modified Capon direction-finding method are found. Reliability of the relationships, which are obtained on the basis of the maximum-likelihood method, is confirmed by the limiting transitions and the results of numerical simulation for typical signal-reception conditions in radio-monitoring and passive radar systems.
